Question

Rakesh had 225 black and green pencils. he had 90 green pencils. what percentage of his pencils was black?

Answer 1

Total number of pencils = 225

Black pencils + green pencils = 225

90 + black pencils = 225

Black pencils = 225 - 90

Black pencils = 135





$\% = \frac{135 \times 100}{225} \\ \\ \% = \frac{13500}{225} \\ \\ \\ = > \% = 60\%$

Answer 2

225 pencils
90 green ones
so black ones = 225-90=135
%= (135×100)/225 =60%(ans)
