There is a ratio of 5 : 4 between two numbers. If 40% of the first number is 12, then what would be 50% of the second number ?
Answer & Solution
Correct Answer:
Option
A
1st number : 2nd number
5 : 4
40% = $$\frac{2}{5}$$
2 units = 12
5 units = 30
So, 1st number = 30
2nd number = $$\frac{30}{5}$$ × 4 = 24
50% of 2nd = 24 × $$\frac{1}{2}$$ = 12
5 : 4
40% = $$\frac{2}{5}$$
2 units = 12
5 units = 30
So, 1st number = 30
2nd number = $$\frac{30}{5}$$ × 4 = 24
50% of 2nd = 24 × $$\frac{1}{2}$$ = 12
