Question 3 of 5
3. Question
Two articles are sold for 3 13860 each. There is loss of 10% on one article and a profit of 10% on the Other. What is the overall profit or loss (in Rs. )?
Correct
Ans: c
Total loss in percentage = x + y – (xy/100)
=10-10 –[(10 ´10)/100] = -1%
Now, SP of two articles = 2´ 13860 = Rs. 27720
And CP of two articles = 27720 ´ [(100/99)] = Rs. 28000
∴Loss = 28000 – 27720 = Rs. 280
Incorrect
Ans: c
Total loss in percentage = x + y – (xy/100)
=10-10 –[(10 ´10)/100] = -1%
Now, SP of two articles = 2´ 13860 = Rs. 27720
And CP of two articles = 27720 ´ [(100/99)] = Rs. 28000
∴Loss = 28000 – 27720 = Rs. 280

Question 5 of 5
5. Question
The monthly incomes of Peter and Paul are in the ratio of 4:3. Their expenses are in the ratio of 3:2. If each saves 6000 at the end of the month, their monthly incomes respectively are (in Rs. )
Correct
Ans: a
Given, monthly incomes of Peter and Paul are in the ratio of 4:3 and their expenses are in the ratio of3:2.
Let their monthly incomes be Rs. 4x and 3x and their expenditures be
R3y and R 2y, respectively.
Then, 4x-3y= 6000
[Because Income – Expenditure = Savings]
And 3x-2y= 6000
4x-3y= 3x-2y
4x-3y= 3y-2y
x= y
4t-3x = 6000, x = 6000
(4x 6000) and (3x 6000). i.e.
Hence, their monthly incomes are
Rs. (4 x 6000) and Rs. (3 x 6000)
Rs. 24000 and Rs. 18000

(4x 6000) and (3x 6000). i.e.
Hence, their monthly incomes are
Rs. (4 x 6000) and Rs. (3 x 6000)
Rs. 24000 and Rs. 18000
