46 + 36 = 82 - 19, 25, 45, 87, 159, ?
200222269250285Option C

19 + (2^2 + 2) = 25

25 + (4^2 + 4) = 45

45+ (6^2 + 6) = 87

87 + (8^2 + 8) = 159

159+(10^2 + 10) = 269 - 83, 124, 206, 370, 698, ?

(+41), (+41 × 2 ), (+41 × 4), (+ 41 × 8)

698 + 41 × 16 = 498 + 656 = 1354 - 168, 94, 152, 392, ?

392×3.5 + 13 = 1385 - The percentage profit earned by selling an article for Rs. 1920 is equal to the percentage loss incurred by selling the same article for Rs. 1280. At what price should the article be sold to make 25% profit?
Rs. 3000Rs. 8000Rs. 5000Rs. 4000Rs. 2000Option E

Let CP is x.

Then (1920-x)/x*100 = (x-1280)/x*100

On solving x = 1600

Selling Price = 1600*125/100 = Rs. 2000 - If ratio of investment A, B and C are in the ratio 3 : 5 : 8 and the time of investment of A, B and C are 100/3 %, 80% and 25% respectively of their investment, and profit of A is 4800 then what will be the profit of C.
2260025600245002750025000Option B

Ratio of profit = 3×3×1/3 : 5×5×4/5 ∶ 8×8×1/4

= 3 ∶ 20 ∶ 16

Profit of C = 4800/3 ×16 = 25600 - Harsha took a loan at a rate of simple interest 7% in the year with an increase of 0.25% in each subsequent year. He paid interest of Rs. 4425 after 4 years. How much loan did he take?
Rs.. 11000Rs. 18000Rs. 13000Rs. 10000Rs. 15000Option E

Total interest = Rs. 4425

Rate = 7% and increasing by 0.25% every year

Let total Loan Amount = P

P = ( 4425 × 100)/( 7 × 1 + 7.25 × 1 + 7.5 × 1 + 7.75 × 1)

= 442500/29.5

= Rs. 15000 - A man can swim at the rate of 12 km/hr in still water and rate of flow of river is 4 km/hr. A wooden log started to flow with the speed of river and man also started to swim downstream from same place and at same time. Man after covering 100 km downstream, returns and started to swim upstream. Man meet the wooden log at a distance of 𝑥 from starting point. Find 𝑥.
70 km40 km60 km50 km30 kmOption D

100/(12 + 4) + (100 – 𝑥)/(12 – 4)

= 𝑥/4 100/16 + (100 – 𝑥)/8

= 𝑥/4 (100 + 200 − 2𝑥)/16

= 𝑥/4 1200 − 8𝑥 = 16𝑥

1200 = 24𝑥

𝑥 = 50 km - A card from a pack of 52 cards is lost. From the remaining cards of the pack, two cards are drawn and are found to be both hearts. Find the Probability of the lost card being a heart?
10/5117/5211/2611/5013/50Option D

Total cards = 52

Drawn cards(Heart) = 2

Present total cards = total cards-drawn cards

= 52 – 2 = 50

Remaining Card = 13-2 = 11

Probability = 11/50
