Step-by-step explanation:

1.SP of 10 pizzas=CP of 11 pizzas

LET CP of each pizza be rs.1

So, CP of 10 pizzas=rs.10

SP of 10 pizzas=rs.11

SP is greater than CP

So, there is a profit.

Profit=11-10=rs.1

Profit per cent= (1/10*100)per cent=10 per cent

answer =10%

2. let the original price be X

increase in price=25% of X

A/Q

X+25%of X=24500

=X+25/100*X=24500

=X+X/4=24500

=(4x+X)/4=24500

=5x/4=24500

=X=24500*4/5

=X=₹19,600

3. 325 km covers in =5 hrs

so 1 km in =5/325 hrs

1300 in = 5/325 x 1300

= 20 hrs
