Question 1

Profit and Loss

Problem

A trader marks his goods 40% above the cost price and allows a discount of 25%. Find his profit or loss percentage.

Solution

Let CP = ₹100
Marked Price = 100 + 40% of 100 = ₹140
Discount = 25% of 140 = ₹35
Selling Price = 140 - 35 = ₹105
Profit = 105 - 100 = ₹5
Profit % = (5/100) × 100 = 5%

Question 2

Time and Distance

Problem

A train 150 m long crosses a platform 250 m long in 20 seconds. Find the speed of the train in km/hr.

Solution

Total distance covered = Length of train + Length of platform = 150 + 250 = 400 m
Time = 20 seconds
Speed = 400/20 = 20 m/s
Speed in km/hr = 20 × (18/5) = 72 km/hr

Question 3

Ratio and Proportion

Problem

Two numbers are in the ratio 5:7. If 8 is subtracted from each, the ratio becomes 3:5. Find the numbers.

Solution

Let the numbers be 5x and 7x.

(5x - 8)/(7x - 8) = 3/5

Cross-multiply:
5(5x - 8) = 3(7x - 8)
25x - 40 = 21x - 24
4x = 16
x = 4

Numbers are 5x = 20 and 7x = 28

Question 4

Time and Work

Problem

A can do a piece of work in 15 days and B can do it in 10 days. They work together for 3 days and then A leaves. In how many more days will B finish the remaining work?

Solution

A's 1 day work = 1/15
B's 1 day work = 1/10
Combined 1 day work = 1/15 + 1/10 = 2/30 + 3/30 = 5/30 = 1/6
Work done in 3 days = 3 × 1/6 = 1/2
Remaining work = 1 - 1/2 = 1/2
B alone finishes remaining work in = (1/2) / (1/10) = 5 days

Question 5

Simple and Compound Interest

Problem

The compound interest on a sum for 2 years is ₹1,050 and the simple interest for the same period at the same rate is ₹1,000. Find the rate of interest.

Solution

Difference between CI and SI for 2 years = CI - SI = 1050 - 1000 = ₹50

This difference equals SI on 1 year's interest.
1 year's SI = 1000/2 = ₹500
Difference = (500 × R)/100 = 50
R = 50 × 100/500 = 10%

Question 6

Blood Relations

Problem

Introducing a boy, a girl said, "He is the son of my mother's only daughter." How is the boy related to the girl?

Solution

"My mother's only daughter" refers to the girl herself (since she is the only daughter).
So "He is the son of the girl" means the boy is the girl's son.

Question 7

Number Series

Problem

Find the missing number in the series: 3, 8, 15, 24, 35, ?

Solution

Differences between consecutive terms: 5, 7, 9, 11, 13
This is an arithmetic sequence with common difference 2.
Next difference = 13
Next term = 35 + 13 = 48

Question 8

Coding-Decoding

Problem

In a certain code, "COMPUTER" is written as "RFUVQNPC" when the letters are reversed and each shifted by one position. If "SYSTEM" follows a similar reversal pattern, how is it coded as "METSYS"?

Solution

Reverse the word "SYSTEM":
S-Y-S-T-E-M reversed is M-E-T-S-Y-S

Question 9

Direction Sense

Problem

Rahul walks 5 km towards East, then turns left and walks 3 km, then turns left again and walks 5 km. How far is he from his starting point?

Solution

Starting point: (0, 0)
Walk 5 km East: (5, 0)
Turn left (facing North), walk 3 km: (5, 3)
Turn left (facing West), walk 5 km: (0, 3)

Distance from starting point = √((0-0)² + (3-0)²) = 3 km

Question 10

Synonym

Problem

Choose the word most similar in meaning to "METICULOUS".

Options: (a) Careless (b) Thorough (c) Quick (d) Vague

Solution

"Meticulous" means showing great attention to detail; very careful and precise. The closest synonym is "Thorough".

Question 11

Sentence Correction

Problem

Identify the error in the sentence: "Neither of the students have completed their assignment."

Solution

"Neither" is singular and requires a singular verb. The correct sentence should be:
"Neither of the students has completed his/her assignment."
