1.14.4
2.16.8
3.16
4.19.2
5.None of these

Explanation :-

Q2. Amit bought a radio set and spent Rs 110 on its repairs. He then sold it to B at 20% profit, B sold it to C at a loss’ of 10 % and C sold it for Rs 1188 at a profit of 10 %. What is the amount for which A bought the radio set?
1.Rs 850
2.Rs 930
3.Rs 890
4.Rs 950
5.None of these

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.

4.86
5.None of these

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.
