1.	If 36 men can built a wall in 12 days, then 16 men can built the same wall in …………….. days. A) 27 B) 18 C) 35 D) 36
Answer» 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 are same (to build a same wall) \(\therefore\) 16 \(\times\) x = 36 \(\times\) 12 \(\Rightarrow\) \(x=\frac{36\times12}{16}=9\times3\) = 27 \(\therefore\) 16 men can built the same wall in 27 days. Correct option is A) 27

Answer»

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 are same (to build a same wall)

\(\therefore\) 16 \(\times\) x = 36 \(\times\) 12

\(\Rightarrow\) \(x=\frac{36\times12}{16}=9\times3\) = 27

\(\therefore\) 16 men can built the same wall in 27 days.

Correct option is A) 27
