Let the numbers p and q be 4x and 3x respectively.
4x = 4 × x
3x = 3 × x
LCM (4x, 3x) = 4 × 3 × x = 36
∴ x = 36/12 = 3
The numbers p and q are 12 and 9 respectively.
∴ Their sum = 12 + 9 = 21
4x = 4 × x
3x = 3 × x
LCM (4x, 3x) = 4 × 3 × x = 36
∴ x = 36/12 = 3
The numbers p and q are 12 and 9 respectively.
∴ Their sum = 12 + 9 = 21
