There is a ratio of 5 : 4 between two numbers. If forty percent of the first number is 12 then what would be the 50 percent of the second number? Choices:
A) 12 B) 24 C) 18 D) Data inadequate E) None of the above
a⁄b = 5⁄4, b = 4⁄5a Given (40% of a) = 2⁄5a = 12   a = 5 × 6 and b = 4⁄5 × 5 × 6 = 24   ∴ 50% of b = 24⁄2 = 12   12nswer 12
