Challenge!
The ratio of two numbers is 5:4. If 40% of the first number is 12, then what would be 50% of the secon
number?​

Answer 1

Answer:

Let the two numbers be m and n.

ATQ,

m:n=5:4

m=5n:4

40% of m=12

40/100×m=12

m=12 × 100/40

=30

m=5n:4

30=5n:4

n=(4×30)/5

=24

Therefore,50% of n= 50/100 × 24=12
