5.None of these

Answer & Explanation

Answer:- 3

Explanation :-

Let the CP of Radio set =X

110% of 9O% of 120% of X = 1188

[(110/100)*(90/100)*(120/100)*X] = 1188

1188X = 118800

X=1000

Money Spent on repair=110

Therefore ,

He purchased it for Rs. (1000 -110) = Rs. 890.

5.None of these

Answer & Explanation

Answer:- 1

Explanation :-

Total CP= Rs. (120 * 80 + 280 + ((40/100) * 120 )+ 72).

=> Rs. (9600 + 280+48 + 72)

=> Rs, 10000.

SP of 120 reams = 108% of Rs. 10000 = Rs. 10800.

SP per ream = Rs. [10800/120] = Rs. 90.
