Answer 1

Answer:

sorry I don't understand your questions

Answer 2

Answer:

70

Step-by-step explanation:

question says , when John's mother was 3/4 of John's present age (assume we are talking about mother's age x years ago), then equation becomes

(M-x) = 3/4 (J)

then, John was 1/5 of his mother's present age :

(J-x) = 1/5(M)

given

J = 48

M-x = 36

M-36 = x-------------------equation 1

J-x = 1/5M

x = (240-M)/5--------------equation 2

equating x from two equations

M-36 = (240-M)/5

M = 70

so mother's present age is 70 ☺️
