*Q1 Option C*

*Let the new S.P. be x, then.*

*(100 – loss%):(1st S.P.) = (100 + gain%):(2nd S.P.)*

*Therefore,
*

*i.e x = 1260*

* *

*Q2. Option C*

*Whenever we get this type of question, we should have formula in mind that,*

*Gain% = (gain/cost)*100*

* *

*Cost = 4700 + 800 = Rs. 5500*

*S.P. = Rs. 5800*

* *

*Profit = 5800 – 5500 = 300*

*Q3. Option B*

*Q4. Option C*

*So before solving this question we will get the C.P. and S.P. of 1 article to get the gain percent.*

*C.P. of 1 orange = 350/100 = Rs 3.50
S.P. of one orange = 48/12 = Rs 4 [note: divided by 12 as 1 dozen contains 12 items]
Gain = 4 – 3.50 = Rs 0.50*

*Q5.Option B*

*Let the cost price = Rs 100*

*then, Marked price = Rs 135*

*Required gain = 8%, *

*So Selling price = Rs 108*

*Discount = 135 – 108 = 27*

*Discount% = (27/135)*100 = 20%*

*Q6. Option C*

*As question states that rate was of pair of articles,*

*So rate of One article = 37.40/2 = Rs. 18.70*

*Let Marked price = Rs X*

*then 85% of X = 18.70*

*therefore, X = 1870/85 = 22*

*Q7. Option C*

*Let the S.P = 100*

*then C.P. = 25*

*Profit = 75*

*Profit% = 75/25 * 100 = 3005*

*Q8. Option C*

*Let the cost price of 1 pen is Re 1 *

*Cost of 8 pens = Rs 8*

*Selling price of 8 pens = 12*

*Gain = 12 – 8 = 4*

*Q9. Option D*

*Let the Cost Price of one article = Rs. 1*

*CP of x articles = Rs. x *

*CP of 20 articles = 20*

*Selling price of x articles = 20*

*Profit = 25% [Given]*

*Q10. Option B*

*Let the cost of Production = Rs. P*

*Then, as per question,*

*Therefore, P = 800*
