Question

Harish bought a gas-chullah for ₹ 900 and later sold it to Archana at a profit of 5 per cent. Archana used it for a period of two years and later sold it to Babita at a loss of 20 per cent. For how much did Babita get it?

Sum

Solution

For Harish: C.P. = ₹ 900, Profit % = 5

S.P. = `((100 + 5)/100) xx 900` = 105 × 9 = ₹ 945

Now, S.P. for Harish would be the C.P. for Archana.

For Archana: C.P. = ₹ 945, Loss % = 20

S.P. = `((100 - 20)/100) xx 945 = 80/100 xx 945` = ₹ 756

Again, S.P. for Archana would be the C.P. for Babita.

So, Babita got the gas-chullah for ₹ 756.
