Answer:

1) Total c.p. is Rs.14000

then s.p. is Rs.16800

It's profit of Rs. 2800

So, gain percent is 20%

5) Let the no. of boys and girls be 8x and 5x

ATQ

No. of girls =160

So,5x=160

x=32

Total no. of students

=32*5+32*8

=160+256

=416 ans..

4) 42 litre petro covers=357km

1litre petrol covers=357/42

so,12 litre cover=357/42*12=102km.
