Solution

The correct option is A 3
Note that $3 \frac{a}{4}$ is a mixed fraction.

$3 \frac{a}{4} =$ $\frac{(3 \times 4) + a}{4} =$ $\frac{12 + a}{4}$

Given, $\frac{(12 + a)}{4}$ = $\frac{15}{4}$

Comparing the numerators on both sides, we get $12 + a = 15$

Therefore, $a = (15 - 12) = 3$

The value of a if 3a4=154 is .

The correct option is A 3Note that 3a4 is a mixed fraction. 3a4= (3×4) +a4= 12 +a4 Given, (12+a)4 = 154 Comparing the numerators on both sides, we get 12+a=15 Therefore, a=(15−12)=3
