Answer 1

Answer:

The number of boys are 7.

Step-by-step explanation:

Let the number of boys be X.

Let the number of girls be Y.

As per question,

Y - X = 2 ,................................... (1)

Money given to each boy =Rs10.

Money given to each girl = Rs 22.

Total money given = Rs280.

Therefore,

10X + 22Y = 280.

10(Y-2) +22Y =280

10Y -20+22Y =280

32Y=300

Y= (300/32) = 9.375

X= 9.375-2 =7.375.
