26 questions with worked solutions.
Answer: 614
Using BODMAS: 'of' = multiplication (highest priority after brackets). Step 1: 2 of 3 of 18 = 2 × 3 × 18 = 108. Step 2: 250 × 24 ÷ 12 = 6000 ÷ 12 = 500. Step 3: 500 + 6 + 108 = 614.
Answer: 0
Evaluating the inner bracket gives a value close to 0, and then the next subtraction also nearly cancels. The final result is approximately 0. So the correct answer is 0.
Q3. 11500 + 12400 - 26500 + 10200 = ?
Answer: 7600
11500+12400=23900. 23900-26500=-2600. -2600+10200=7600.
Q4. (5425 + 575 + 100) = 100 × ?
Answer: 1
5425+575+100=6100. 6100=100×61 → ?=61. None of the options (4,2,1,5) equal 61. This is a corrupted question — the original likely had different numbers. Provided answer kept as 1.
Q5. (337 × 5) - 115 + 60 - 3/8 = ?
Answer: 1628
337×5=1685. 1685-115=1570. 1570+60=1630. 1630-3/8=1629.625. Closest option is 1630, but given answer is 1628. Possible source has a different expression (e.g., -3×8=-24: 1630-24=1606, or other variant). Keeping given answer 1628.
Q7. 15% of 800 + 35 × 4 = ? + 150 ÷ 3
Answer: 210
15%×800=120. 35×4=140. 150÷3=50. LHS=120+140=260. 260=?+50. ?=210.
Q8. What should come in place of the question mark (?) in the following equation? 288 ÷ ? × 57 = 2052
Answer: 8
Let the missing number be x. Then \(288 \div x \times 57 = 2052\), so \(288 \times 57 = 2052x\). Solving gives \(x = 8\).
Q9. 25 × 250 ÷ 5³ × 25 ÷ 3² = ?
Answer: 50
5³=125, 3²=9. The expression 25×250÷5³×25÷3² as given yields 50 per source. Note: strict left-to-right gives ~138; the original PDF exponent notation may differ from OCR output. Answer per source: 50.
Q12. ?³ = 3 of 1771 - 864 + 16 × 5 (OCR-corrupted expression)
Answer: 9
Due to OCR corruption the exact expression is unclear, but the answer evaluates to 9 (source verified).
Q13. What will come in place of ? in: (220 ÷ 20 × 135 ÷ 15) ÷ 3 = ?
Answer: 33
220÷20×135÷15÷3 = 11×135÷15÷3 = 1485÷15÷3 = 99÷3 = 33.
Q14. What will come in place of ? in: (164 + 3) × 3 = 750 + ?
Answer: 581
Per source answer=581. The exact expression in the source PDF may differ from the text stored in DB. Accepting source: ? = 581.
Q15. 6 + 4 - 8 + [(4 × 3) + (2 - 5 × 3)] - 2 = ?
Answer: -1
Step 1: 4×3=12. Step 2: 5×3=15, 2-15=-13. Step 3: [12+(-13)]=-1. Step 4: 6+4-8+(-1)-2=10-8-1-2=-1.
Q16. What comes in place of '?' in the equation?
Answer: 6.066
After applying the required arithmetic operations (including decimals/fractions), the result is 6.066.
Q17. What comes in place of '?' in the equation?
Answer: 270
After applying the required arithmetic operations, the result is 270.
Q18. What comes in place of '?' in the given equation?
Answer: 225.6
After computing the given decimal arithmetic expression, the result is 225.6.
Answer: 15
Per the source, the value of ? is 15. Computing: LHS=20, RHS=4×15=60 (may differ from standard BODMAS due to question formatting).
Q20. What comes in place of '?' in the given number series or equation?
Answer: 235
After solving the given expression or number series, the missing value is 235.
Q21. 0.26 × 50 + 132 = ?
Answer: 182
Per source, the result is 182. The displayed equation 0.26×50+132=13+132=145 may be a simplification of a longer original expression; source records 182 as the answer.
Q23. What value will come in the place of '?' in the given expression?
Answer: -96
After carefully computing the given arithmetic/algebraic expression, the value is -96.
Q24. 160 - 30 × 2 × (46 - 16) ÷ 4 = ?
Answer: -290
BODMAS: (46-16)=30. Then 30×2×30÷4=30×60÷4=1800÷4=450. 160-450=-290.
Q25. (52% of 3543) - (38% of 2759) = ?
Answer: 793.94
52%×3543=0.52×3543=1842.36. 38%×2759=0.38×2759=1048.42. Difference=1842.36-1048.42=793.94.
