Question 1 of 20
1. Question
A circular road runs around a circular ground. If the radius of the ground is 5.5 m and the difference between the circumference of the outer circle and that of the inner circle is 110m, then the area of the road is?
Correct
Answer c
Radius of the ground (r) = 5.5 m
The difference between the circumference of the outer circle and that of the inner circle is 110m
= > 2πR- 2πr = 110
= > 2*(22/7)*(R-r) = 110
= > R-r = 17.5
= > R- 5.5= 17.5
= > R= 23 m
The area of the road is,
=> πR^{2} – πr^{2}
=> (22/7) (23^{2} – 5.5^{2})
= > (22/7) (23+5.5) (23-5.5)
= > (22/7)*28.5* 17.5
= > 1567.5 m^{2}
Incorrect
Answer c
Radius of the ground (r) = 5.5 m
The difference between the circumference of the outer circle and that of the inner circle is 110m
= > 2πR- 2πr = 110
= > 2*(22/7)*(R-r) = 110
= > R-r = 17.5
= > R- 5.5= 17.5
= > R= 23 m
The area of the road is,
=> πR^{2} – πr^{2}
=> (22/7) (23^{2} – 5.5^{2})
= > (22/7) (23+5.5) (23-5.5)
= > (22/7)*28.5* 17.5
= > 1567.5 m^{2}

Question 3 of 20
3. Question
The ratio of A and B’s salary is 5:7. If B’s salary is increased by 35%, then his salary becomes 28350. What is the salary of A?
Correct
Answer a
The ratio of A and B’s salary is 5:7(5x, 7x)
According to the question,
7x*(135/100) = 28350
X= 28350*(100/ (135*7))
X= 3000
A’s salary = 5x = 15000
Incorrect
Answer a
The ratio of A and B’s salary is 5:7(5x, 7x)
According to the question,
7x*(135/100) = 28350
X= 28350*(100/ (135*7))
X= 3000
A’s salary = 5x = 15000
Question 4 of 20
4. Question
In a mixture of 50 litres, the ratio of milk to water is 3:2. If this ratio is to be 5:7, then what is the quantity of water needed to be added?
Correct
Answer d
Total Quantity = 50 litres
The ratio of milk to water= 3:2
Milk= 30 litres, Water= 20 litres
According to the question,
30/(20+x) = 5/7
42 = 20+x
X= 22 litres
So 22 litres of water should be added.
Incorrect
Answer d
Total Quantity = 50 litres
The ratio of milk to water= 3:2
Milk= 30 litres, Water= 20 litres
According to the question,
30/(20+x) = 5/7
42 = 20+x
X= 22 litres
So 22 litres of water should be added.

Correct
Answer a
= > (69/100)*730 +409.3 + (25/100)*x = 1923
= > 503. 7 + 409. 3 + (1/4)*x = 1923
= > (1/4)*x = 1923 – 503. 7 – 409. 3
= > (1/4)*x = 1010
= > x = 4040
Incorrect
Answer a
= > (69/100)*730 +409.3 + (25/100)*x = 1923
= > 503. 7 + 409. 3 + (1/4)*x = 1923

Answers:
Answer c
Radius of the ground (r) = 5.5 m
The difference between the circumference of the outer circle and that of the inner circle is 110m
= > 2πR- 2πr = 110
= > 2*(22/7)*(R-r) = 110
= > R-r = 17.5
= > R- 5.5= 17.5
= > R= 23 m
The area of the road is,
=> πR^{2} – πr^{2}
=> (22/7) (23^{2} – 5.5^{2})
= > (22/7) (23+5.5) (23-5.5)
= > (22/7)*28.5* 17.5
= > 1567.5 m^{2}
Answer c
Let Ravi’s monthly salary be x,
According to the question,
X*(50/100)*(60/100) = 12336
X = 41120
Answer a
The ratio of A and B’s salary is 5:7(5x, 7x)
According to the question,
7x*(135/100) = 28350
X= 28350*(100/ (135*7))
X= 3000
A’s salary = 5x = 15000
Answer d
Total Quantity = 50 litres
The ratio of milk to water= 3:2
Milk= 30 litres, Water= 20 litres
According to the question,
30/(20+x) = 5/7
42 = 20+x
X= 22 litres
So 22 litres of water should be added.
Answer b
