the gain will be of the extra 1.5 % .

so now find the 1.5 % of 3500.

Dear Student,

Gain to B = ₹ 157.5

Simple interest to B is given by -

SI(B) = 3500 × 10/100 × 3

SI(B) = ₹ 1050

Simple interest to C is given by -

SI(C) = 3500 × 11.5/100 × 3

SI(C) = ₹ 1207.5

So gain to B is calculated by -

Gain to B = 1207.5 - 1050

Gain to B = ₹ 157.5

Hence, gain to B is ₹ 157.5.

Thanks dear. Hope this helps you..
