A mother is twice as old as her son. If 20 years ago, the age of the mother was 10 times the age of the son, what is the present age of the mother?

• 1. 38 years

• 1. 40 years

• 1. 43 years

• 1. 45 years

Answer explanation

The Correct answer is (D)

Explanation:

Let the age of son = X years

∴Age of mother would be =2X

As per question 20 years ago;

10 (X -20) = 2X - 20

10X - 200 = 2X - 20

10X - 2X= - 20 + 200

8X = 180

X=180/8= 22.5 years

∴Age of mother = 22.5 * 2 = 45 years

A train moving at speed of 80 km/hr crosses a pole in 7 seconds. Find the length of the train.

• 1. 150 m

• 1. 165 m

• 1. 175 m

• 3. 170 m

  
  

Answer explanation

The correct option is (C).

Answer with explanation:

Length of the train is equal to the distance covered by train to cross the pole. So, we will find the distance travelled by the train in 7 seconds by applying the following formula:

Distance= Speed x Time

Speed is given in Km/hr so we will convert it into m/s as answers are given in meters.

Speed=90*(5/18) = 25 m/s

Time = 7 seconds

Distance = 25 * 7= 175 meters

Which number should come next in the series, 48, 24, 12, ......?
