Let sum be invested in Bank A be x and in Bank C be Rs. 5000 - x So `(x xx 4 xx 2)/100 + ((5000-x) xx 5 xx 2)/100 = 420` `OR (8x)/100 + (50000-10x)/100 = 420` `or (50000-2x)/100=420 ` `or 50000-2x = 42000` `or 2x = 8000` `x = 4000` So Sum invested with Bank A = Rs. 4000 & Sum invested with Bank C = Rs. 1000 Hence the required ratio = 4000:1000 = 4:1
