Explanation:

Quantity 1:

Let cost price of bat is x.

Then S.P. =85x/100=17x/20.

If he had bought it for 20 % less:

C.P. =80x/100=4x/5

And, S.P. =17x/20+ 147.2 =(17x + 2944)/20

Now,

(S.P. – C.P.)/C.P × 100 = 35

[(17x + 2944)/20-4x/5]/((4x/5) )× 100 = 35

= (17x + 2944 – 16x)/(20 )×5/4x × 100 = 35

=(x + 2944)/20×125/x= 35

=( x + 2944)/4×25/x= 35

= 25x + 73600 = 140x

= x =73600/115= 640

Cost price of Bat = Rs 640

Quantity 2:

C.P of A =225×100/(100+20)×100/(100+25)

=225×100/120×100/125=150

Rs.150

Hence Quantity 1>Quantity2

Hence, option 3 is the correct answer.
