Question 1076646
from what i understand, .....


she gives 20% to archana and 40% to mukti.


that's total of 60% she gave away.


she has 40% left.


let x = the amount she started with.


.4 * x = 30


solve for x to get x = 30 / .4 = 75


she started with 75.


she gives 20% to archana = 15.


she gives 40% to mukti = 30.


she gave away a total of 45.


she has 75 - 45 = 30 left.


looks ok to me.
