Correct option is (A) 27
Given that 36 men can built a wall in 12 days.
\(\therefore\) Total work = 36 \(\times\) 12
Let 16 men can built the wall in x days.
\(\therefore\) Total work = 16 \(\times\) x
\(\because\) Both work...
Correct option is (A) 50
Food stock = 500 \(\times\) 70 = 35000
Let after 200 more joined the camp the food stock is sufficient for x many days.
\(\therefore\) x (500+200) = 500 \(\times\) 70
\(\Rightarrow\) \(x=\frac{500\times70}{700}=50\)
\(\therefore\) Food...
Correct option is (D) \(\frac{(a+1)^2}{a+2}\)
Work done by (a+1) works in (a+1) days = (a+1) (a+1)
\(=(a+1)^2\)
Number of days required to complete the same work by (a+2) members \(=\frac{\text{Total work}}{a+2}\)
\(=\frac{(a+1)^2}{a+2}\)
