Answer:

11.Convert the mixed fractions into proper fractions.

2.1/2 dozen eggs =5/2

22 3/4rs =91/4rs

now 5/2×91/4=455/8

90/1-455/8

=720-455/8

265/8

=33.125rs

Therefore 33.125rs is left with him.

12. Perimeter of an isosceles triangle =18

long=5 3/4cm

Perimeter =l/2-b/2

long 5 3/4=23/4

18=23/4-b/2

b/2=23/4-18

b/2=5.75

b=5.75×2

b=11.5cm

Therefore the third side of triangle is 11.5cm.

13. 1m cost of cloth =17 1/3=51/3

12 1/4m=?

let the cost be x

12 1/4=40/4

x=51/3×49/4

x=2499/12

x=208.25

Therefore the cost of 12 1/4m cloth is 208.25rs.
