Answer 2

Answer:

36

Step-by-step explanation:

Given :

300 cadets = 42 days

50 more persons joined

To find :

How many days will the provision last if 50 more persons join

According to the question :

Let the no. of. Days be ' x '

No. of. Cadets No. of. Days

↦300 42

↦300 + 50 ⬆️ x ⬇️

If No. of. Cadets increase ⬆️ , No. of. Days will ⬇️.

Equation will be :

⟹ 300 × 42 = ( 300 + 50 ) × x

⟹ 300 × 42 / ( 300 + 50 ) = x

⟹ 300 × 42 / 350 = x

⟹ 12600 / 350 = x

⟹ x = 36
