S.P. of 120 reams = 108% of Rs. 10000 = Rs. 10800.

S.P. Per ream = Rs. [ 10800 ] = Rs. 90.

32) Investment = Rs. (20 x 8 + 10) = Rs. 170. Receipt =

Gain % = ( x 100)% = 35.29% = 35.3%

Loss to the manufacturer = Rs. [38000 - (25 x 1000)]

35) C.P. = Rs. (600 + 600 x 6 x 4 ) = Rs. 612. Gain


100 x 12

Gain % = [ 153 x 100]% = 25%
