1000+ Mathematics Aptitude Test Questions and Answers Pdf - 1

Ans: C

Dividing 5000 by 73, the remainder is 36, The number greater than 5000 is obtained by adding to 5000 the difference of divisor and the remainder.

∴ The required number = 5000 + (73 - 36) = 5037.

Ans: B

Let the numbers be a and b.

Then a² + b² = 68 and (a - b)² = 36

Now, (a - b)² = 36

⇒ a² + b² - 2ab = 36

⇒ 68 - 2ab = 36

⇒ 2ab = 32 ⇒ ab = 16.

Ans: D

$${303375} /{25}$$ = $${303375 × 4} / {25 × 4}$$ = $${2113500} / {100}$$ = 12135.

On multiplying other numbers by 4, the digits at units and tens places will not be zero.

Ans: A

10x + y - 10y - x = 9

⇒ 9(x - y) = 9

⇒ x - y = 1.

Ans: C

Last digit of dividend = 1

Last digit of divisor = 7

∴ Last digit of quotient should be 3

4767 × 3 = 14301

4767 × 20 = 95340

4767 × 100 = 476700

∴ 4767 × (3 + 20 + 100) = 586341

Missing digits are 586.
