Question

plz give me answer and send me plz OK on paper

Answer 1

• Let the no. of male be 8 x and no. of female be 5 x .

A/Q, 8 x = 104

    x = 104/8 = 13

No. of female = 5 x = 5 x 13 = 65

• Let their ages be 5 x and 7 x .
• 18 years ago,

their was

• (5 x - 18 )
• (7 x - 18)

A/Q, (5 x - 18 ) / ( 7 x - 18 ) = 8 /13

    65 x - 234 = 56 x - 144

    65 x - 56 x = 234 - 144

   9 x = 90

 x = 10

Their present ages are 5 x 10 and 7 x 10.

                                     = 50 and 70
