⇒ 62 = ?2
⇒ ? = 6
∴ The value of ? is 6
What will come in the place of question mark (?) in the given expression?
450 × 30 + 1500 × 20 = ?% × 43500
100
50
200
150
250
Correct answer
100
Why this answer is correct
Concept used:
Follow BODMAS rule to solve this question, as per the order given below
Calculations:
450 × 30 + 1500 × 20 = ?% × 43500
⇒ 13500 + 30000 = (?/100) × 43500
⇒ 43500 = ? × 435
⇒ ? = 100
∴ The value of ? is 100
What will come in the place of the question mark ‘?’ in the following question?
8974 + 3567 – 8976 – 3565 + 8652 = ?
7652
8752
8662
8652
None of these.
Correct answer
8652
Why this answer is correct
Concept used:
Follow BODMAS rule to solve this question, as per the order given below,
Calculation:
8974 + 3567 – 8976 – 3565 + 8652 = ?
⇒ 8974 + 3567 + 8652 – 3565 – 8976 = ?
⇒ 21193 – 12541 = ?
⇒ 8652 = ?
∴ The value of ? is 8652
Alternate Method
8974 + 3567 – 8976 – 3565 + 8652 = ?
⇒ 8974 – 8976 + 3567 – 3565 + 8652 = ?
⇒ -2 + 2 + 8652 = ?
⇒ ? = 8652
∴ The value of ? is 8652

What is the difference between the total production of Ford and Tata motors in the given years?
40,000
20,000
26,000
35,000
25,000
Correct answer
20,000
Why this answer is correct
Calculations:
Total Production of cars from Ford = (240000 + 160000 + 200000 + 180000)
⇒ 780000
Total Production of cars from Tata Motors = (220000 + 200000 + 180000 + 200000)
⇒ 800000
∴ Difference = 800000 - 780000
⇒ 20000
The difference between the total production of Ford and Tata motors in the given years is 20,000.

2,60,000
2,50,000
2,55,000
Correct answer
2,10,000
Why this answer is correct
Calculations:
Total Production of cars from Honda = (200000 + 180000 + 220000 + 240000)
