Question 121

One fourth of two-fifth of 30% of a number x is equal to 15. Find 20% of the same number.

Solution

According to ques,

=> $$\frac{1}{4} \times \frac{2}{5} \times \frac{30}{100} \times x=15$$

=> $$\frac{3x}{100}=15$$

=> $$x=15 \times \frac{100}{3}=500$$

$$\therefore$$ 20% of $$x$$ = $$\frac{20}{100} \times 500$$

= $$20 \times 5=100$$

=> Ans - (A)
