Question

Find C. P, when : S. P = Rs 800, loss per cent = 15 per cent​

Answer 1

Find the gain or loss per cent when: (i) CP ... Gain = SP - CP = ( 12800 - 12000) = Rs. 800 ... SP of 16 spoons = CP of 15 spoons = Rs 15

Answer 2

$CP = \frac {( SP \times 100 )} {( 100 – loss~percentage )} \\ \\ \implies \frac{(800 \times 100)}{100-15} \\ \\ \implies \frac{80000}{85} \\ \\ \implies 941$
