Question

The cost of the T-shirt was $Rs.120$ in January. the same T-shirt now cost $Rs.150.$ Find the percentage increases in the cost of the T-shirt.

Answer 1

Given: Original cost of T-shirt $=Rs.120$

Final cost of T-shirt after increment $=Rs.150$

Increase in rate $=$ Final $-$ original price $=Rs.(150-120)=Rs.30$

Percentage increase in cost of T-shirt $=\frac{\text{increase in rate}}{\text{original rate}}\times 100\%$

$=\frac{30}{120}\times 100\%$

$=\frac{100}{4}\%$

$=25\%$
