Average marks Av = M(h) - 30 ___________(1)
marks In hindi = m(h)
marks in science = 62
Average marks = 62 + M(h) / 2 ____________(2)
by 1 and 2
M(h) - 30 = 62 + M(h) / 2
2M(h) - 60 = 62 + M(h)
M(h) = 122
marks in hindi = 122
marks In hindi = m(h)
marks in science = 62
Average marks = 62 + M(h) / 2 ____________(2)
by 1 and 2
M(h) - 30 = 62 + M(h) / 2
2M(h) - 60 = 62 + M(h)
M(h) = 122
marks in hindi = 122
