Question

Mark the correct alternative in the following question:

If 21 cows eat as much as 15 buffaloes, then how many cows will eat as much as 35 buffaloes?

(a) 45 (b) 49 (c) 56 (d) 54

Answer 1

As, the number of cows that eat as much as 15 buffaloes = 21

⇒ The number of cows that eat as much as 1 buffalo = $\frac{21}{15}=\frac{7}{5}$

So, the number of cows that eat as much as 35 buffaloes = $\frac{7}{5}\times 35$ = 7 × 7 = 49

Hence, the correct alternative is option (b).
