Answer» LET The number of toffees with P be ‘x’ ∴ S has x/2 toffees And, Q has 4/5 × (P + S) =(4/5)(x + x/2) = 6x/5 toffees ∴ R has 2/3 ×(P + Q + S) = 2/3 × (x + x/2 + 6x/5) = 2/3 × (3x/2 + 6x/5) = 9x/5 toffees ∴ x + x/2 + 6x/5 + 9x/5 = 135 ∴ (10x + 5x + 12x + 18x) = 1350 ∴ 45X = 1350 ∴ x = 30 ∴ S will have 30/2 = 15 toffees |
