An aircraft carries 2880 litres of fuel distributed in three tanks in the ratio 3 : 4 : 5. The quantity in the 5 parts tank is

A) 720 litres
B) 800 litres
C) 1000 litres
D) 1200 litres

Correct Answer:




D) 1200 litres

Description for Correct answer:

Let quantity in three tanks be 3x, 4x and 5x litres

\( \Large \therefore 3x+4x+5x = 2880 \)

=> 12x = 2880

=> \( \Large x = \frac{2880}{12} = 240 \)

Hence quantity in the 5 parts tank

= \( \Large 240 \times 5 = 1200\ litres.\)
