Question

Kumar can hop 36 times in 40 seconds. How many times can he in 60 seconds ?

• A. 60
• B. 54
• C. 72
• D. 46

Answer 1

The correct option is B

54

Number of times he can hop in 40 seconds = 36

Let x be the number of times he can hop in 60 seconds

Write the ratio for given hops to seconds as below :

$\frac{36\text{hops}}{40\text{seconds}}$ = $\frac{x\text{hops}}{60\text{seconds}}$

$\frac{36\text{hops}}{40\text{seconds}}\times 60\text{seconds}=x$

$\frac{36}{40}\times 60=x$

$0.9\times 60=x$

$54=x$

So, required answer is $x=54$

Hence he can hop 54 times in 60 seconds
