Expected Questions in RBI Office Attendant Quant 2026
Let us understand the most important topics one by one.
Simplification Problems
Simplification questions test your calculation speed. These are direct questions. If you practice well, you can solve them quickly in the exam.
Problem 1
Question:
110% of 220 − 75% of 300 = x − 17
Solution:
110% of 220 = 1.1 × 220 = 242
75% of 300 = 0.75 × 300 = 225
Now substitute:
242 − 225 = x − 17
17 = x − 17
x = 17 + 17
x = 34
Final Answer: x = 34
Problem 2
Question:
123 × (8697 ÷ 223) = x² + 36
8697 ÷ 223 = 39
Now multiply:
123 × 39
123 × (40 − 1)
= 4920 − 123
= 4797
So,
4797 = x² + 36
x² = 4797 − 36
x² = 4761
√4761 = 69
Final Answer: x = 69
Problem 3
Question:
440 − (50% of 340) + 91 = x²
50% of 340 = 170
Now solve:
440 − 170 + 91
= 270 + 91
= 361
x² = 361
x = 19
Final Answer: x = 19
Problem 4
Question:
45% of 360 − 64 = x − 14
45% of 360 = 162
Now solve:
162 − 64 = x − 14
98 = x − 14
x = 98 + 14
x = 112
Final Answer: x = 112
Problem 5
Question:
75% of 60 + 25% of 160 = (x/100) × 170
75% of 60 = 45
25% of 160 = 40
45 + 40 = 85
85 = (x/100) × 170
85 ÷ 170 = x/100
0.5 = x/100
x = 50
Final Answer: x = 50
Number Series (Wrong Number Identification)
These questions check your pattern recognition skill. Look at differences first.
Problem 1
Series: 120, 250, 500, 1030
Pattern: ×2 + 10
120 × 2 + 10 = 250
250 × 2 + 10 = 510
Given number is 500. It should be 510.
Wrong Number: 500
Problem 2
Series: 12, 25, 42, 61, 84, 112
Check differences:
25 − 12 = 13
42 − 25 = 17
61 − 42 = 19
84 − 61 = 23
These are prime numbers.
Next prime after 23 is 29.
84 + 29 = 113
Given number is 112.
Wrong Number: 112
Problem 3
Series: 3, 5, 11, 23, 43
Check differences:
5 − 3 = 2 (1×2)
11 − 5 = 6 (2×3)
23 − 11 = 12 (3×4)
43 − 23 = 20 (4×5)
Pattern is n × (n+1).
The series follows the pattern correctly.
Problem 4
Series: 300, 179, 110, −59, −423
Differences:
300 − 179 = 121 (11²)
179 − 110 = 69
110 − (−59) = 169 (13²)
The pattern suggests square of prime numbers.
The number 110 breaks the pattern.
Wrong Number: 110
Problem 5
Series: 15, 65, 125, 133
15 × 4 + 5 = 65
65 × 2 − 5 = 125
Next step should be:
125 × 1 + 5 = 130
Given number is 133.
Wrong Number: 133
Quadratic Equation Comparison
These questions require solving two equations and comparing x and y.
Problem 1
x² = 16
y² + 9y + 20 = 0
x = ±4
Second equation factors:
(y + 4)(y + 5) = 0
y = −4, −5
In all cases, x ≥ y
Problem 2
x² + 25x + 144 = 0
y² + 36y + 320 = 0
x = −16, −9
y = −20, −16
In all cases, x ≥ y
Problem 3
25x² − 25x + 6 = 0
49y² − 77y + 30 = 0
x = 3/5, 2/5
y = 6/7, 5/7
Both values of y are greater than x.
Conclusion: y > x
Problem 4
x² − 15x + 30 = 3 − 3x
y² = 64
x = 9, 3
y = 8, −8
Both relations exist.
Conclusion: A relationship cannot be established
Problem 5
x² − 16x − 57 = 0
y² − 9y + 20 = 0
x = 19, −3
y = 4, 5
Both relations exist.
Conclusion: A relationship cannot be established
Arithmetic Word Problems
These are practical and scoring.
Problem 1: Income and Savings
Total income ₹8400
Ratio 6:8:7
One part = ₹400
Income:
P = ₹2400
Q = ₹3200
R = ₹2800
Savings ratio 3:2:4
Q saves ₹400
One part = ₹200
Savings:
P = ₹600
Q = ₹400
R = ₹800
Expenditure:
P = ₹1800
Q = ₹2800
R = ₹2000
Final Ratio = 9 : 14 : 10
Problem 2: Combined Ratios
First:Second = 2:3
Second:Third = 5:8
Combined ratio = 10 : 15 : 24
Total sum = 1176
One part = 24
Third number = 24 × 24 = 576
Problem 3: Exam Ratio
Initial ratio = 25:4
After changes, equation formed and solved gives
x = 10
Total students = 29 × 10 = 290
Problem 4: Mixture
Total 120 kg
Ratio 7:5
Sugar = 70 kg
Salt = 50 kg
After changes:
Sugar = 90 kg
Salt = 40 kg
New ratio = 9 : 4
Problem 5: Complex Mixture
After calculation, x = 5
Initial water from Vessel B = 18 × 5
= 90 liters
Problem 6: Percentage Target
Assume 100 questions
Answered = 60
Correct = 24
Target = 60 correct
Need 36 more correct
Remaining = 40
Required percentage = 90%
Problem 7: Alligation
Income decreased by 10%
Expenditure decreased by 12%
Savings increased by 14%
Using alligation:
Expenditure : Savings = 12 : 1
Income = 13 parts
Income : Expenditure = 13 : 12
Smart Preparation Strategy for RBI Office Attendant Quant 2026
