Ans: C

- 95 ÷ 19 = $${-95} / {19}$$ = - 5.

Ans: D

Let the ten’s digit be x and the unit’s digit be y.

Then, (10x + y) - (10y + x)

= 9x - 9y = 9(x - y), which is divisible by 9.

Ans: B

Let the required odd numbers be n, (n + 2) and (n + 4).

Then n + (n + 2) + (n + 4) = 3n + 6 = 3 (n + 2), which is always divisible by 3.

But n = 1 ⇒ 3(n + 2) = 3 × 3 = 9 which is not divisible by any of 2, 5 and 6.

Hence Only II is true.

Ans: D

$${(Dividend) – (Remainder)} / {Quotient}$$ = Divisor.

Divisor = $${(940 - 25)} / {15}$$ = $${915} / {15}$$ = 61.

Ans: C

348 × 265 = (350 - 2) × 265 = (350 × 265) - (2 × 265)

= {(300 + 50) × 265} - 530 = (300 × 265) + (50 × 265) - 530

= 79500 + 13250 - 530 = 92750 - 530 = 92220.
