Answer

This is a Branching question. (Amended)

LCM 

2/9 = 14/63

1/7 = 9/63

    Wife / T children  Left   Total  
R1    14u + 1040          49u – 1040       63u  
R2   27u 9u 36u

49u – 1040 = 36u

49u – 36u = 1040

13u = 1040

1u = 1040 ÷ 13 = 80

a)

63u = 63 × 80 = 5040

b)

9u = 5040 ÷ 7 = 720
