roy is now 8 years older than julia and half of that amount older than kelly . if in 2 years , roy will be 3 times as old as julia , then in 2 years what would be roy ’ s age multiplied by kelly ’ s age ?
r = j + 8 = k + 4 r + 2 = 3 ( j + 2 ) ( j + 8 ) + 2 = 3 j + 6 j = 2 r = 10 k = 6 in 2 years ( r + 2 ) ( k + 2 ) = 12 * 8 = 96 the answer is d .
multiply(add(divide(subtract(add(8, 2), multiply(3, 2)), subtract(3, const_1)), add(8, 2)), subtract(add(divide(subtract(add(8, 2), multiply(3, 2)), subtract(3, const_1)), add(8, 2)), divide(8, const_2)))
