Question 76
Read the statements and conclusions carefully.

So only conclusion (I) follows.
β
Answer: A. Only conclusion (I) follows

Question 82
Select the set in which the numbers are related in the same way as in the given sets:
(6,3,16), (14,8,29)
A. (19,12,38)
B. (14,87,26)
C. (6,15,21)
D. (16,25,31)
π· Trick
There are three values inside (1st, 2nd, 3rd)
3rd = 1st + 2nd + 7
This is the key trick here.
(6, 3, 16)
16 = 6 + 3 + 7
16 = 16
(14, 8, 29)
29 = 14 + 8 + 7
29 = 29
Let’s pick Option A: (19, 12, 38)
38 = 19 + 12 + 7
38 = 38
β
Answer: A. (19,12,38)
Question 83
A dealer buys two articles X and Y for βΉ500 each. He marks each at the same price. He sells X by giving two successive discounts of 50% and 20% and still earns βΉ100 profit. If he sells Y at a single discount of 60%, then what is the profit percentage on Y?
A. 20%
B. 28%
C. 36%
D. 40%
π΄ Given
Cost Price (CP) of X = βΉ500
Cost Price (CP) of Y = βΉ500
Marked Price (MP) of both = same
For X:
Discounts: 50% and 20%
Profit = βΉ100
Discount Trick (IMPORTANT)
CP = 500
Let MP = x
Before discounts: Let’s try to find out the real price before discount. We always assume real price as 1 if we haven’t given any.
Final Price =
50% β 1 – 50% = 0.5
28% β 1 – 20% = 0.8
SP/FP = MP Γ 0.5 Γ 0.8 = 0.4x
Profit:
0.4x β 500 = 100
π 0.4x = 600
π x = 1500
For Y: Same way like above =
SP = 40% of 1500 = 600
Profit = 600 β 500 = 100
β
Answer: A. 20%
