उत्तर
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.
