1) 9 cm    2) 12 cm    3) 18 cm        4) 3 cm       5) None of these

4a=4(l+b)

72=4(12+b)

b=6

then side of square=72/4=18 ,

a-b=18-6=12cm

2. Find the average of the following set of scores.

253, 124, 255, 534, 836, 375, 101, 443, 760

1) 12,000  2)12,500   3)12,800 4)13,000   5)None of these

1/4 th of Ajay=father and 2/3 rd of Ajay’s brother= father

then Ajay’s brother 1/4th salary =12800 then total salary =12800×4=51,200

then father salary= 51200/2 *5=128000

Ajay’s salary= 128000/4=32000

thrfre his savings=32000/8 *3=12,000Rs
