Answer:

  • let he got x marks in hindi and y marks in English.
  • According to first condition, x+y=80........(1)
  • according to second condition x=y+20,hence x-y=20.......(2)
  • add equation (1) and (2.)

a+ b=80

+a-b=20

-------------

2a=100

a=50

  • put a=50 in equation( 1)
  • a+b=80
  • 50+b=80
  • b=80-50
  • b=30
  • mark in hindi is 50 and English is 30
