Answer:
Ruchi: 150
sindhu: 300
Explanation:
lets say Ruchi had r amount of money. that means Sindhu had 2r (double).
we know that Ruchi spent 60, and Sindhu spent 210.
so there ending amounts would be:
Ruchi: r - 60
Sindhu: 2r - 210
since they ended up with the same amount we can set them equal to each other and solve for r.
r - 60 = 2r - 210
150 = r
so Ruchi had 150 and Sindhu had 300.
