Question

Mr a sells a bicycle to Mr b at a profit of 20% and Mr B sells it to Mr c at profit of 25% if Mr c pays Rupees 1500 what did Mr A pay for it

Answer 1

Cp of b=

$100 \div 100 + profit\% \times sp = 100 \div 100 + 25 \times 1500 = 1200$

Cp of a =
$100 \div 100 + profit\% = cp = 100 \div 100 + 25 \times 1200 = 960$
So a cost price =960
