the sum of the numbers is 98 . if the ratio between the first and the second be 2 : 3 and that between the second and third be 5 : 8 , then find the second number ?
given ratios 2 : 3 5 : 8 10 : 15 : 24 the second number = 98 / ( 10 + 15 + 24 ) * 15 = 30 answer is b
divide(multiply(98, lcm(3, 5)), add(multiply(8, 3), add(multiply(5, 2), multiply(5, 3))))
