Description:
Since A, B and C saved 20%, 15% and 25% respectively then their saving ratio 7/6 / 9 Here, 20% of A = 7 (অনুপাতের ৭) So, 100% of A = 35
15% of B = 6 So, 100% of B = 40.
25% of C = 9 So, 100% of C = 36
So, A : B : C =35:40:36
Sum = 35 + 40 + 36 = 111 Therefore salary of B = 33300 * 40/111 = Tk 12000
