Correct Answer: 35 years

Solution : Let the present age of Rahim be x years and her daughter be y years.
Given: x = 5y
According to the question,
x + 7 = 3(y + 7)
⇒ x + 7 = 3y + 21
Putting the value of x, we get:
5y + 7 = 3y + 21
⇒ 2y = 14
⇒ y = 7
So, x = 5y = 5 × 7 = 35
Hence, the correct answer is 35 years.

Correct Answer: 1993 - 94

Solution : The difference in the number of students who passed to those who failed in 1991 - 92 = 150 - 100 = 50
The difference in the number of students who passed to those who failed in 1992 - 93 = 200 - 100 = 100
The difference in the number of students who passed to those who failed in 1993 - 94 = 300 - 50 = 250
The difference in the number of students who passed to those who failed in 1994 - 95 = 250 - 100 = 150
The difference in the number of students who passed to those who failed in 1995 - 96 = 300-100 = 200
The difference in the number of students who passed to those who failed was maximum in 1993 - 94.
Hence, the correct answer is 1993 - 94.

Correct Answer: 27

Solution : Given: A racing car going at an average speed of 108 km/hr takes 15 minutes to complete a lap on a racing track.
So, the distance travelled by the racing car in 15 minutes = speed × time = $108×\frac{15}{60}=27$ km
To complete the lap in 12 minutes, the speed will be $\frac{27}{\frac{1}{5}}=135$ km/hr
So, it should increase the speed by (135 – 108) = 27 km/hr
Hence, the correct answer is 27.
