The price of each article of type P, Q, and R is ₹240, ₹180 and ₹120, respectively. A shopkeeper buys articles of each type in the ratio 1 : 2 : 3 for ₹4,800. How many articles of type Q did he purchase?

A. 8
B. 10
C. 12
D. 14

Ratio Purchase
Ratio = 1 : 2 : 3 → total = 6 units
Cost per unit:
1 × 240 + 2 × 180 + 3 × 120
= 240 + 360 + 360
= 960
Given total = 4800

4800/960 = 5
So Q articles: P : Q : R = 1 : 2 : 3
2 × 5 = 10
✅ Answer: B. 10
👉 Trick: Find cost of one ratio block.

Read the statements and conclusions carefully.
Statements:
All lanterns are lights.
Some lights are lamps.
All lamps are useful.
Conclusions:
(I) Some useful things are lights.
(II) All lanterns are useful.

A. Only conclusion (I) follows
B. Only conclusion (II) follows
C. Both conclusions follow
D. Neither conclusion follows

Syllogism
Solution
From the statements:
All lanterns are lights.
Some lights are lamps.
All lamps are useful.

Since some lights are lamps and all lamps are useful, it follows that some useful things are lights.
But nothing says all lanterns are lamps or useful, so the second conclusion does not follow.
Correct answer: A. Only conclusion (I) follows

Six people A, B, C, D, E and F live on six different floors of a building numbered 1 to 6 from bottom to top.
Only one person lives below C.
B lives immediately above C.
A lives above B but below E.
D lives immediately below F.
Who lives on floor number 2?

A. A
B. B
C. C
D. D

Solution
Only one person lives below C ⟹ C is on floor 2.
B lives immediately above C ⟹ B is on floor 3.
A lives above B but below E ⟹ A is on floor 4 and E is on floor 6.
D lives immediately below F ⟹ remaining floors 1 and 5 go to D and F, with D below F.
So floor 2 is occupied by C.
Quick trick: Use the “only one below” clue first; it locks the placement quickly.
Correct answer: C

Find the mode of the following grouped data. Give the answer correct to 2 decimal places.

A. 33.29
B. 34.29
C. 35.29
D. 36.29

Mode (Grouped Data)
Formula:
$\text{Mode} = l + \frac{f_1 – f_0}{2f_1 – f_0 – f_2} \times h$

Modal class: 30–40 = 20
$l = 30$
$f_1 = 20$
$f_0 = 14$
$f_2 = 12$
$h = 10$ = (40 – 30)
Let’s put values:
$30 + \frac{20 – 14}{2(20) – 14 – 12} \times 10 \\ 30 + \frac{6}{40 – 26} \times 10 \\ 30 + \frac{6 \times 10}{14} \\ 30 + 4.2857$
= 34.29
✅ Answer: B. 34.29
Quick trick: The modal class is the class with the highest frequency.

A woman travelled at a speed of 24 m/min for 80 minutes, and at a speed of 60 m/min for 40 minutes. Her average speed for the entire journey is:

A. 34 m/min
B. 36 m/min
C. 38 m/min
D. 40 m/min

Average Speed
Distance:
24 × 80 = 1920,

Total time: 3+3 = 6
Average speed: 300/6 = 50 km/h
Quick trick: Add distances and times separately, then divide.
Correct answer: B. 50 km/h

At what rate per annum simple interest will a sum become 2.5 times itself in 10 years?

A. 12%
B. 15%
C. 18%
D. 20%

Simple Interest
Amount = 2.5P → SI = 1.5P
We start putting interest after the end of 1 year, so 2.5 becomes 1.5.
$SI = \frac{P \times R \times T}{100} \\ 1.5P = \frac{P \times R \times 10}{100} \\ \frac{1.5}{R} = \frac{P \times 10}{100 \times P} \\ \frac{1}{R} = \frac{10}{100 \times 1.5} \\ R = \frac{150}{10}$
⇒ R = 15%
✅ Answer: B. 15%

Ben has ₹2,100 with him. He divides this amount between his two sons, Lokesh and Rovesh, and asks them to invest their respective shares at a compound interest rate of 10% per annum, compounded annually. It is observed that Lokesh’s investment amounts to the same value after 5 years as Rovesh’s investment does after 6 years. How much did Ben give to Rovesh?

A. ₹1,000
B. ₹1,050
C. ₹1,100
D. ₹1,150

I Investment
Assume the value 1 and 10% = 1.1
Given:
Lokesh (5 yrs) = Rovesh (6 yrs)
L(1.1)⁵ = R(1.1)⁶
⇒ L = R(1.1)¹
⇒ L = 1.1R
Total: L + R = 2100
1.1R + R = 2100
⇒ 2.1R = 2100
⇒ R = 2100/2.1
⇒ R = 1000
✅ Answer: A. 1000

In an election, 75% of the registered voters cast their vote and 20% of the votes polled were found invalid. The winning candidate got 75% of the valid votes and won by a margin of 300 votes. How many voters were registered?

A. 900
B. 1000
C. 1100
D. 1200

Election
Let voters = x
Votes cast 75% of x = 0.75x
Invalid 20% of 0.75x = 0.15x
Valid = 0.75x – 0.15x = 0.60x

Winning candidate got 75% of valid votes, so losing candidate got 25%.
Margin = 50% of valid votes: 0.5
0.5 × 0.60x = 0.30x
Given Margin 300 votes:
⇒ 0.30x = 300
⇒ x = 300/0.30
⇒ x = 1000
Quick trick: Margin between 75% and 25% of valid votes is exactly 50% of valid votes.
✅ Answer: B. 1000
