1000+ Bank of Nova Scotia Aptitude Test Questions & Answers - 1

Ans: C

Second son’s share = Rs.$$(10800 × {4}/{12})$$ = Rs.3600.

Money distributed between the two daughters

= Rs.[3600 – (1000 + 600)] = Rs.2000.

First daughter’s share = Rs.$$(2000 × {11}/{20})$$ = Rs.1100.

Second daughter’s share = Rs.$$(2000 × {9}/{20})$$ = Rs. 900.

Ans: C

Second : Third = 9 : 16,

Third : First = 4 : 1 = 16 : 4.

∴ Second : Third : First = 9 : 16 : 4.

Second number = $$(116 × {9}/{29})$$ = 36.

Ans: B

Let the numbers be 4x and 5x.

Then, their L.C.M. = 20x.

20x = 180 or x = 9.

∴ Smaller number = 4x = 4 × 9 = 36.

Ans: B

Let A = x, B = 2x, C = 3x. Then, $${x + 2x + 3x} / {3}$$ = 600

⇒ 2x = 600 ⇒ x = 300.

So, A = 300, B = 600, C = 900.

New value of A = 110% of 300 = 330.

New value of B = 80% of 600 = 480

New average = 105% of 600 = 630.

New value of C = (630 × 3) - (330 + 480) = 1080.

∴ Increase in value of C = (1080 - 900) = 180.

Ans: B

Let Mr. Sharma’s expenditure be Rs.3x and his savings be Rs.2x.

Income = Rs.(3x + 2x) = Rs.5x.

Increased income = 110% of Rs.5x = Rs.5.5x.

Increased expenditure = 112% of Rs.3x = Rs.3.36x.

Increased savings = Rs.(5.5x - 3.36x) = Rs.2.14x.

Increase in savings = Rs.(2.14 - 2) x = Rs.0.14x.

∴ Increase % = $$({0.14}/{2x} × 100)$$% = 7%.
