If 9 is \(\frac{3}{4}\) of n, and if m = \(\frac{5}{6}\) of n, find m.

If 9 is \(\frac{3}{4}\) of n, and if m = \(\frac{5}{6}\) of n, find m.

A 10

B 12

C 14.4

D 15

Solution

Correct Answer: Option A

Solution:

দেওয়াআছে, \(\frac{{3n}}{4} = 9\) => \(n = \frac{{4 \times 9}}{3} = 12\) n = 12

আবার, m = \(\frac{5}{6} \times n\) => m = \(\frac{5}{6} \times 12\) = 10 m = 10
