Question
A person 'M' is 5 years younger than 'N' and also 9
years less than twice the age of 'P'. Given that the ages of 'N' and 'P' are in the ratio 7:4, determine the current age of 'M'.Solution
ATQ;
Let 'N' = 7x, and 'P' = 4x
'M' = 'N' – 5 = 7x – 5
Also, 'M' = 2('P') – 9 = 2(4x) – 9 = 8x – 9
Hence, 7x – 5 = 8x – 9
x = 4
'M' = 7(4) – 5 = 28 – 5 = 23
