leela and kumar shared a sum of money.
leela has $90 less than kumar
kumar gave 1/7 of his money to leela
after that, leela has $10 more than kumar.
how much did leela have at first.

Kumar : 7u
Leela : 7u - $90

When Kumar gives Leela 1/7 if his money

Kumar : 7u - 1u = 6u
Leela : 7u - $90 + 1u = 8u - $90

8u - $90 = 6u + $10
2u = $100
1u = $50

Amy Leela had at first
= $350 - $90
= $260
