A camp of 150 soldiers has food for 400 days. After 50 days, 100 more soldiers join the camp. For how many days will the food last from then onwards?
Answer & explanation
Correct answer: option 2
Formula to be used here,
\( { M}_{1 } \) x \( { D}_{1 } \) = \( { M}_{2 } \) x \( { D}_{2 } \)
where M = No. of men, D = No. of days,
⇒ Putting values in the formula,
⇒ 150 x 350 = 250 x \( { D}_{2 } \)
⇒ \( { D}_{2 } \) = 210 days.
