Question

jyoti & her friends were selling boxes of hankies. they sold 4 more boxes in the second week than they did in the first week. during the third week, they double the sale of their second week. altogether, they sold 352 boxes. how many boxes they sell in the third week.

Answer 1

Let first week they sold x no. Of boxes
Now on second week no. Will be (x+4)
3rd week it must be 2(x+4)
now total no. Is given as 352
so we have
x + x+4+ 2(x+4)= 352
4x+12=352
4x= 340
x=85
As no. Of boxes sold = 2(x+4)
2*(85+4)
2*89
178 boxes
