Question

the amount of petrol in a tank is twice of that in another tank.if we draw out 25 litres from first and add it to other,the amount of petrol in both the tanks will be the same. find the amount of petrol in each tank now.

Answer 1

Let us assume that the petrol in one tank is X ltrs, then petrol in another tank is 2X Litres.

The equation we get from the problem is:

2X - 25 = X + 25

2X - X = 25 + 25

X = 50 Litres.

Since the petrol in one tank is 50 Litres, then petrol in other tank will be 2X = 2x 50 = 100 Litres.

Ans: 100 Litres and 50 Litres.
