the ratio of ages of aman , bren , and charlie are in the ratio 5 : 8 : 7 respectively . if 5 years ago , the sum of their ages was 75 , what will be the age of aman 10 years from now ?
"let the present ages of aman , bren , and charlie be 5 x , 8 x and 7 x respectively . 5 x - 5 + 8 x - 5 + 7 x - 5 = 75 x = 3 present age of aman = 5 * 3 = 15 aman ' s age 10 years hence = 15 + 10 = 25 answer = b"
add(multiply(divide(add(multiply(8, const_3), 75), add(add(5, 8), 7)), 8), 10)
