If 25% of three-seventh of 26% of a number is 145.5, what is the number?

A 4987

B 5784

C 5223

D 4741

Solution

Correct Answer: Option C

Given, 

 

25% of three-seventh of 26% of a number is 145.5

 

Let the required number be 'N'

 

i.e, \(\frac{25}{100}\times\;\frac37\times\;\left(\frac{26}{100}\times\;N\right)=\;145.5\)

N =\(\frac{145.5\times\;7\times\;10000}{75\times\;26}\)

=> N = 5223.07
