Question

some articles are bought at 2 for ₹ 15 and sold at 3 for ₹ 25 find the gain percentage​

Answer 1

$\sf \Large Solution!!$

CP of 2 articles = Rs 15

CP of 1 article = Rs 7.5

SP of 3 articles = Rs 25

SP of 1 article = Rs 8.3

SP>CP

Profit = SP - CP

Profit = Rs 8.3 - Rs 7.5

Profit = Rs 0.8

Profit% = $\sf \dfrac{Profit}{CP}\times 100$

Profit% = $\sf \dfrac{0.8}{7.5}\times 100$

Profit% = 10.6%
