Directions (6 – 10): What value should come in the place of question mark (?) in the following questions?
35 % of ? – 2652 ÷ 17 – 2023 ÷ 7 = 52
Correct
Answer: a)
(35/100)*x – (2652/17) – (2023/7) = 52
(7x/20) – 156 – 289 = 52
(7x/20) = 52 + 156 + 289
(7x/20) = 497
X = 497*(20/7) = 1420
Incorrect
Answer: a)
(35/100)*x – (2652/17) – (2023/7) = 52
(7x/20) – 156 – 289 = 52
(7x/20) = 52 + 156 + 289
(7x/20) = 497
X = 497*(20/7) = 1420
Question 8 of 20
8. Question
Directions (6 – 10): What value should come in the place of question mark (?) in the following questions?
[(42.8 × 23) ÷ 46 – 750 ÷ 150] = 4 × ?
Correct
Answer: c)
(42.8*23)/46 – (750/150) = 4x
21.4 – 5 = 4x
16.4 = 4x
X = 16.4/4 = 4.1
Incorrect
Answer: c)
(42.8*23)/46 – (750/150) = 4x
21.4 – 5 = 4x
16.4 = 4x
X = 16.4/4 = 4.1
Question 9 of 20
9. Question
Directions (6 – 10): What value should come in the place of question mark (?) in the following questions?
27 % of 4500 – 32 % of 250 = ? – √289 % of 1200
Correct
Answer: b)
(27/100)*4500 – (32/100)*250 = x – (17/100)*1200
1215 – 80 = x – 204
1215 – 80 + 204 = x
X = 1339
Incorrect
Answer: b)
(27/100)*4500 – (32/100)*250 = x – (17/100)*1200
1215 – 80 = x – 204
1215 – 80 + 204 = x
X = 1339
Question 10 of 20
10. Question
Directions (6 – 10): What value should come in the place of question mark (?) in the following questions?
74 % of 350 + 46 % of 1550 = ? – (13)^{3}
Correct
Answer: d)
(74/100)*350 + (46/100)*1550 = x – 2197
259 + 713 = x – 2197
X = 259 + 713 + 2197
X = 3169
Incorrect
Answer: d)
(74/100)*350 + (46/100)*1550 = x – 2197
259 + 713 = x – 2197
X = 259 + 713 + 2197
X = 3169
Question 11 of 20
11. Question
Perimeter of a rectangle is x meter and circumference of a circle is 8 meter more than the perimeter of the rectangle. Ratio of radius of circle and length of the rectangle is 1: 2 and ratio of length and breadth of rectangle is 7: 3. Find the length of the rectangle?
Correct
Answer: c)
Perimeter of rectangle = 2*( l + b) = x
2l + 2b = x and 2πr = x + 8
r/l = 1/2 and l/b = 7/3
r : l : b = 7 : 14 : 6 (7y, 14y, 6y)
2πr = x + 8
2πr = 2l + 2b + 8
2*(22/7)*7y = 2*14y + 2*6y + 8
44y = 28y + 12y + 8
44y – 40y = 8
4y = 8
Y = 2
Length of the rectangle = 14y = 28 m
Incorrect
Answer: c)
Perimeter of rectangle = 2*( l + b) = x
2l + 2b = x and 2πr = x + 8
r/l = 1/2 and l/b = 7/3
r : l : b = 7 : 14 : 6 (7y, 14y, 6y)
2πr = x + 8
2πr = 2l + 2b + 8
2*(22/7)*7y = 2*14y + 2*6y + 8
44y = 28y + 12y + 8
44y – 40y = 8
4y = 8
Y = 2
Length of the rectangle = 14y = 28 m
Question 12 of 20
12. Question
A, B and C started a business with their investments in the ratio 1: 2: 4. After 6 month, A invested the half amount more as before and B invested same the amount as before while C withdrew 1/4th of his investment. Find the ratio of their profits at the end of the year?
Harish brother is 3 years elder than Harish. Harish father was 28 years of age when Harish sister was born while Harish mother was 26 years of age when Harish was born. If Harish sister was 4 years of age when Harish brother was born, then what was the age Harish father when Harish brother was born?
Correct
Answer: d)
Let Harish age = x
Harish brother’s age = x + 3
Harish mother’s age = x + 26
Harish sister’s age = (x + 3) + 4 = x + 7
Harish Father’s age = (x + 7) + 28 = x + 35
Age of Harish father when Harish brother was born
= > x + 35 – (x + 3) = 32 years
Incorrect
Answer: d)
Let Harish age = x
Harish brother’s age = x + 3
Harish mother’s age = x + 26
Harish sister’s age = (x + 3) + 4 = x + 7
Harish Father’s age = (x + 7) + 28 = x + 35
Age of Harish father when Harish brother was born
= > x + 35 – (x + 3) = 32 years
Question 14 of 20
14. Question
Ramesh borrowed Rs. 30000 from a bank at a rate of 12% per annum for two years at simple interest and lends the same money to Mahesh at the rate of 12% for two years but he charged compound interest. What is the overall gain by Ramesh?
Correct
Answer: c)
The difference between the simple interest and compound interest for 2 years
Diff = Sum*(r/100)^{2}
So, the overall gain by Ramesh = 30000*(12/100)^{2} = Rs. 432
Incorrect
Answer: c)
The difference between the simple interest and compound interest for 2 years
Diff = Sum*(r/100)^{2}
So, the overall gain by Ramesh = 30000*(12/100)^{2} = Rs. 432
Question 15 of 20
15. Question
In an examination, Rakesh secured 52% marks and failed by 23 marks. In the same exam, Radhika secured 64% marks and scored 34 more than the passing marks. What is the score of Mohan in the same exam, who secured 84% marks?
Correct
Answer: d)
Let the maximum marks be x,
Here passing mark is equal. So,
(52/100)*x + 23 = (64/100)*x – 34
23 + 34 = (12/100)*x
X = 57*(100/12) = 475
The score of Mohan = 475*(84/100) = 399
Incorrect
Answer: d)
Let the maximum marks be x,
Here passing mark is equal. So,
(52/100)*x + 23 = (64/100)*x – 34
23 + 34 = (12/100)*x
X = 57*(100/12) = 475
The score of Mohan = 475*(84/100) = 399
