an amount of rs. 1638 was divided among a, b and c, in the ratio 1 / 2: 1 / 3: 1 / 4. find the share of a?
multiply(divide(1638, add(add(2, 3), 4)), 4)
let the shares of a , b and c be a , b and c respectively . a : b : c = 1 / 2 : 1 / 3 : 1 / 4 let us express each term with a common denominator which is the last number divisible by the denominators of each term i . e . , 12 . a : b : c = 6 / 12 : 4 / 12 : 3 / 12 = 6 : 4 : 3 . share of a = 6 / 13 * 1638 = rs . 756 answer : c
