Question

125 students have food sufficient for 18 days, if 25 more students join them, how long will the food last now.

Answer 1

Pupils in the beginning = 125

More pupils joined = 25

Total pupils = 125 + 25 = 150

Food is sufficient for 125 pupils for = 18 days

Food will be sufficient for 1 pupil for = 18 x 125 days (less pupil more days)

and food will be sufficient for 150 pupils = $\dfrac { 18 \times 125 }{ 150 }$ days (more pupil more days)

= $\dfrac { 18 \times 5 }{ 6 }$ 15 days
