Question 89

Sachin and Sanjana are calculating 23 % of 800.

Now, calculate 52 % of 700 using both the ways described above.
Which way do you find easier?

Answer 1

First way $52\%of700=\left(1\%of700\right)\times 52=(\frac{1}{100}\times 700)\times 52=(0.01\times 700)\times 52=7\times 52=364$
Second way
$52\%of700=\frac{52}{100}\times 700=0.52\times 700=364$
So, second way, we have to find easier.
