Question

4. At the University student party, there were 10 more girls than boys. The boys paid Rs.

20 each, while the girls' Rs. 15 each, and the total receipts were Rs. 1620. How many

girls and boys were there at the party? ​

Answer 1

Answer:

no. of boys = x

money paid by boys = 20x

no. of girls = x + 10

money paid by girls = (x + 10)×15

1620 = 20x + 15x +150

35x = 1470

x = 42

no. of boys =42

no. of girls = 52

Answer 2

Answer:

53 and

Step-by-step explanation:

Let the no of boys is X

So the no of girls is X+10

Total amount paid by boys is X×20=20X

and, total amount paid by 15(X+10)

According to the question,

20X+15(X+10) =1620

20X+15X+150=1620

35X=1620-150=1470

X= 1470/35= 43

no boys 43

no girls 53
