The 5th part of a number when divided by 3 yields three times half of tenth part of half of 80. What is the number?

Correct option is C

Given:

The 5th part of a number when divided by 3 yields three times half of tenth part of half of 80.

Solution:

Let the number be x.

​$$\frac {\frac x5}{ 3 }= 3 \times \frac12 \times \frac1{10} \times \frac12 \times 80$$​​

​$$\frac x { 15} = 3 \times\frac{1}{20}\times 40$$​​

​$$\frac x { 15} = 6$$​​

x = 90

Therefore, the number is 90.
