5% of 420 × ? % of 1 50 = 252
Let us consider the unknown percentage to be x.
5% =$$\frac{5}{100}$$
5% of 420 = $$\frac{5\times420}{100}$$ = 21
21 x (x % of 150) = 252
x % of 150 = 252 ÷ 21 = 12
$$\frac{x}{100}$$=$$\frac{12}{150}$$
x = $$\frac{12\times100}{150}$$ =$$\frac{12\times2}{3}$$ = 8.
Hence the correct option is Option D.
