1000+ Aptitude Questions for Bank PO, SO, Clerk, SSC, UPSC Exams - 1

Ans: B

Market value of Rs.100 stock = Rs. 92

∴ Market value of Rs. 125000 stock = Rs. $$({92}/{100} × 125000)$$ = Rs. 115000

∴ An investment of Rs. 115000 is required to purchase Rs. 125000 of 8% stock at 92.

Ans: B

Face value = Rs. (50 × 20) = Rs. 1000

Dividend = Rs. $$({1000 × 19} / {4 × 100})$$ = Rs. $$({95}/{2})$$

Investment = Rs. (45 × 20) = Rs. 900

Rate = Rs. $$({95 × 100}/{2 × 900})$$ = 5.28%.

Ans: A

Income from first stock = Rs.$$({7}/{98} × 245000)$$ = Rs.17500

We have to find the amount realized on selling this stock.

Amount realized on selling Rs.98 stock = Rs.100

Amount realized on selling Rs.245000 stock

= Rs.$$({100}/{98} × 245000)$$ = Rs. 250000

This amount is invested in 9% stock at 125.

∴ Income from second stock = Rs.$$({9}/{125} × 250000)$$ = Rs. 18000

Hence, increase in income = Rs. (18000 – 175000) = Rs.500.

Ans: B

Purchase price of first stock = Rs.(99 + 3) = Rs.102.

∴ Income on first stock = Rs.$$({5}/{102} × 50490 )$$ = Rs.2475

Sale price of stock = Rs.(102 - 3) = Rs.99

∴ Amount received by selling the first stock

= Rs. $$({99}/{102} × 50490)$$ = Rs.49005

Purchase price of the second stock = Rs.(96 + 3) = Rs.99

∴ Income on second stock = Rs.$$({8}/{99} × 49005)$$ = Rs.3960

Hence, change in income = Rs.(3960 - 2475) = Rs.1485

Ans: C

Number of shares sold = $${7500}/{100}$$ = 75

Proceeds from sale of Rs.7500 stock

= Rs.[(105.50 – 0.5) × 75] = Rs.7875.

Number of new shares purchases = $$({7875} / {124.50 + 0.50})$$ = $$({7875}/{125})$$ = 63

Original income = 10% of Rs.7500 = Rs.750.

New income = 14% of Rs.6300 = Rs.$$({14}/{100} × 6300)$$ = Rs.882.

∴ Change in income = Rs.(882 – 750) = Rs. 132.
