The radius of the circle is equal to two-third of the side of the square. The area of the square is 441 sq cm. Find the perimeter of a circle?
Correct
Answer c
Radius = (2/3)*side
Area of square = a^{2} = 441
Side (a) = 21 cm
Radius = (2/3)*21 = 14 cm
Perimeter of the circle = 2πr
= > 2*(22/7)*14
= > 88 cm
Incorrect
Answer c
Radius = (2/3)*side
Area of square = a^{2} = 441
Side (a) = 21 cm
Radius = (2/3)*21 = 14 cm
Perimeter of the circle = 2πr
= > 2*(22/7)*14
= > 88 cm
Question 13 of 20
13. Question
The sum of two numbers is 3420. If 12 % of one number is equal to 28 % of another number, find the largest number.
Correct
Answer a
Let two numbers be x and y,
X + Y= 3420
12% of one number = 28 % of another number
(12/100)*x = (28/100)*y
x/y = 28/12 = 7/3
x : y = 7 : 3
10’s = 3420
1’s = 342
Largest number = 7’s = 342*7 = 2394
Incorrect
Answer a
Let two numbers be x and y,
X + Y= 3420
12% of one number = 28 % of another number
(12/100)*x = (28/100)*y
x/y = 28/12 = 7/3
x : y = 7 : 3
10’s = 3420
1’s = 342
Largest number = 7’s = 342*7 = 2394
Question 14 of 20
14. Question
4 years ago, the age of mother is 4 times that of his son. After 6 years, mother and son is in the ratio of 5:2. Find the ratio of ages of mother and son, after 13 years?
Correct
Answer c
4 years ago, Mother: Son = 4: 1 <= (4x, x)
After 6 years, M: S =5: 2
According to the question,
4x + 10/ x+10 = 5/2
8x + 20 = 5x + 50
3x = 30
X = 10
Present ages of mother and son = (4x+4, x+4) = 44, 14
After 13 years, Ratio of mother and son = (44+13, 14+13)
= > 57: 27 = 19: 9
Incorrect
Answer c
4 years ago, Mother: Son = 4: 1 <= (4x, x)
After 6 years, M: S =5: 2
According to the question,
4x + 10/ x+10 = 5/2
8x + 20 = 5x + 50
3x = 30
X = 10
Present ages of mother and son = (4x+4, x+4) = 44, 14
After 13 years, Ratio of mother and son = (44+13, 14+13)
= > 57: 27 = 19: 9
Question 15 of 20
15. Question
Three pipes A, B and C can fill a tank in 8 hours. After working at it together for 3 hours, C is closed and A and B can fill the remaining part in 6 hours. How much time taken by C to fill the tank alone?
Correct
Answer b
Three pipes A, B and C can fill a tank in 8 hours.
A, B and C’s 1 hour work=1/8
A, B and C’s 3 hour work= 3/8
Remaining work= 1-3/8 =5/8
The remaining part will be filled by A and B in 6 hours. Then,
= > (5/8) *(A+B) = 6
= > (A+B)’s whole work= 48/5 hr
(A+B)’s 1 hour work= 5/48
A, B and C’s 1 hour work=1/8
C’s 1 hour work= (A+B+C)-(A+B)
= > (1/8) – (5/48)
= > 1/48
C can fill the tank in 48 hours.
Incorrect
Answer b
Three pipes A, B and C can fill a tank in 8 hours.
A, B and C’s 1 hour work=1/8
A, B and C’s 3 hour work= 3/8

A, B and C’s 1 hour work=1/8
C’s 1 hour work= (A+B+C)-(A+B)
= > (1/8) – (5/48)
= > 1/48
C can fill the tank in 48 hours.

Failed students of college x in 2006 = 400*(50/100) =200
Failed students of college x in 2006 is 25% more than the passing student in college x in 2010,
200 = (125/100)* Passing students of college x in 2010
Passing students of college x in 2010 = 200*(100/125) = 160
(40/100)* total students = 160
Total students = 160*(100/40) = 400
Failed students of college X in 2010 = 400*(60/100) = 240
