Answer:

Nawman = 59 years

Phukan = 41 years

Explanation:

P = N - 18

P + N = 100

(N - 18) + N = 100

2N = 100 + 18

2N = 118

N = 118 : 2

N = 59 years

P = (59 - 18) years

P = 41 years

Explanation:

phukan = x

Nanwan = y

let this be a simultaneous equation.

x - y = 18.... equation i

x + y = 100.... equation ii

subtract equation i from equation ii

= 2y = 118

y = 59

substitute y = 59 in equation ii to get x

x + 59 = 100

x = 100- 59

x = 41

Nanwan = 59, Phukan = 41
