Directions (Q. 6 – 10): What should come in place of question mark (?) in the following questions?
888 ÷ 12 + 2756 ÷ 13 + 1472 ÷ 16 = x % of 720
Correct
Answer c
(888/12) + (2756/13) + (1472/16) = (x/100)*720
74 + 212 + 92 = (x/100)*720
378 = (x/100)*720
X = (378*100) /720
X = 52.5
Incorrect
Answer c
(888/12) + (2756/13) + (1472/16) = (x/100)*720
74 + 212 + 92 = (x/100)*720

15^{2} – 34^{2} + (8029 + 671) ÷ ? = 229
Correct
Answer a
225 – 1156 + (8700/x) = 229
(8700/x) = 229 – 225 + 1156
(8700/x) = 1160
X = 8700/1160
X = 7.5
Incorrect
Answer a
225 – 1156 + (8700/x) = 229
(8700/x) = 229 – 225 + 1156
(8700/x) = 1160
X = 8700/1160

X = 3
Question 11 of 20
11. Question
A, B and C together have Rs. 16400. If 2/15^{th} of A’s amount is equal to 3/5^{th} of B’s amount and 3/4^{th} of B’s amount is equal to 9/16^{th} of C’s amount, then how much amount does A have?
Correct
Answer a
A + B + C = Rs. 16400
(2/15)* A = (3/5)* B
(A/B) = (3/5) * (15/2) = 9/2
(3/4)* B = (9/16)* C
(B/C) = (9/16) * (4/3) = ¾
41’s = 16400
1’s = 400
27’s = 10800
Incorrect
Answer a
A + B + C = Rs. 16400
(2/15)* A = (3/5)* B
(A/B) = (3/5) * (15/2) = 9/2
(3/4)* B = (9/16)* C
(B/C) = (9/16) * (4/3) = ¾
41’s = 16400
1’s = 400
27’s = 10800
Question 12 of 20
12. Question
P, Q and R entered into a partnership by investing Rs. 60000, Rs. 70000 and Rs. 80000 respectively. After 5 months, P withdraws 30 % of the initial investment and Q invested 15000 more.

5 years ago, the ages of Anu and Hema are in the ratio of 6 : 5. Three years ago, Anu’s age is equal to Hema’s age after 2 years. Then find the present age Anu?
Correct
Answer b
5 years ago, Anu : Hema = 6 : 5(6x , 5x)
Present ages of Anu and Hema = 6x + 5, 5x + 5
Three years ago, Anu’s age is equal to Hema’s age after 2 years,
= > 6x +2 = 5x + 7
= > x = 5
Present age of Anu = 6x + 5 = 35 years
Incorrect
Answer b
5 years ago, Anu : Hema = 6 : 5(6x , 5x)
Present ages of Anu and Hema = 6x + 5, 5x + 5
Three years ago, Anu’s age is equal to Hema’s age after 2 years,
= > 6x +2 = 5x + 7
= > x = 5
Present age of Anu = 6x + 5 = 35 years
Question 14 of 20
14. Question
A can do a piece of work in 20 days, B can do it in 25 days. They started the work together but A left 5 days before the completion of the work. The work has finished in?
Correct
Answer c
(x – 5)/20 + x/25 = 1
(5x – 25 + 4x)/100 = 1
9x – 25 = 100
9x = 125
X = 125/9 = 13 8/9 days
Incorrect
Answer c
(x – 5)/20 + x/25 = 1
(5x – 25 + 4x)/100 = 1
9x – 25 = 100
9x = 125
X = 125/9 = 13 8/9 days
Question 15 of 20
15. Question
The difference between length and breadth of the rectangle is 16. The length of the rectangle is equal to the side of the square, if the area of the square is 1024 Sq m. Find the perimeter of the rectangle?
Correct
Answer a
Length – Breadth = 16
Length = Side of square
Area of square = 1024 = a^{2}
Side (a) = 32 m = length
According to the question,
32 – b = 16
Breadth = 32-16 = 16 m
Perimeter of the rectangle = 2(l + b) = 2(32 + 16)
= > 2(48)
= > 96 m
Incorrect
Answer a
Length – Breadth = 16
Length = Side of square
Area of square = 1024 = a^{2}
Side (a) = 32 m = length
According to the question,
32 – b = 16
Breadth = 32-16 = 16 m
Perimeter of the rectangle = 2(l + b) = 2(32 + 16)
= > 2(48)
= > 96 m
Question 16 of 20
16. Question
Directions (Q. 16 – 20): Study the following graph carefully and answer the questions given below it.
If income of company A in 2004 was equal to its expenditure in 2007, what was the respective ratio between the expenditure of company in 2004 and 2007?
Correct
Answer b
Let the Income of Company A in 2004 and expenditure of company A in 2007 be x,
Expenditure of Company A in 2004
= > x = exp*(140/100)
= > exp = 100x/140
Required ratio = (100x/140) : x = 5 : 7
Incorrect
Answer b
Let the Income of Company A in 2004 and expenditure of company A in 2007 be x,
Expenditure of Company A in 2004
= > x = exp*(140/100)
= > exp = 100x/140
Required ratio = (100x/140) : x = 5 : 7
Question 17 of 20
17. Question
Directions (Q. 16 – 20): Study the following graph carefully and answer the questions given below it.
If income of company B in 2006 was Rs. 21.5 lakhs and ratio of income of company A and B was 4 : 5, what was approximate expenditure of company A in 2006?
Correct
Answer e
Income of company A in year 2006 = 4/5 x 21.5 = Rs. 17.2 lakh
If expenditure of company A in year 2006 is Rs. X
Profit % = {(I – E)/E} *100
Then, 65 = [17.2-x/x]*100
=> x = 1720/165 = Rs. 10 Lakh (Approx.)
Incorrect
Answer e
Income of company A in year 2006 = 4/5 x 21.5 = Rs. 17.2 lakh
If expenditure of company A in year 2006 is Rs. X
Profit % = {(I – E)/E} *100
Then, 65 = [17.2-x/x]*100
=> x = 1720/165 = Rs. 10 Lakh (Approx.)
Question 18 of 20
18. Question
Directions (Q. 16 – 20): Study the following graph carefully and answer the questions given below it.
If total expenditure of both companies in 2008 was Rs. 15 lakhs and ratio of expenditure of company A and B in that year was 3 : 2 respectively what was income of company B in that year?
Correct
Answer b
Expenditure of Company B = 2 x 15/5 = Rs. 6 lakh
If income of company B in year 2006 is Rs. x, then
50 = {(x-6)/6}*100
x = Rs. 9 lakh
Incorrect
Answer b
Expenditure of Company B = 2 x 15/5 = Rs. 6 lakh
If income of company B in year 2006 is Rs. x, then
50 = {(x-6)/6}*100
x = Rs. 9 lakh
Question 19 of 20
19. Question
Directions (Q. 16 – 20): Study the following graph carefully and answer the questions given below it.

Correct
Answer c
Let the Income of Company A in 2003 and expenditure of company B in 2004 be x,
Expenditure of Company A in 2003
= > x = exp*(140/100)
= > exp = 100x/140
Income of Company B in 2004
= > Inc = x*(150/100)
Ratio = 100x /140 : 150x /100 = 10 : 21
Incorrect
Answer c
Let the Income of Company A in 2003 and expenditure of company B in 2004 be x,
Expenditure of Company A in 2003
= > x = exp*(140/100)
= > exp = 100x/140
Income of Company B in 2004
= > Inc = x*(150/100)
Ratio = 100x /140 : 150x /100 = 10 : 21
