Option 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

6. 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. 3000
Rs. 8000
Rs. 5000
Rs. 4000
Rs. 2000
Option 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

7. 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.
22600
25600
24500
27500
25000
Option 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

8. 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.. 11000
Rs. 18000
Rs. 13000
Rs. 10000
Rs. 15000
Option 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

9. 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 km
40 km
60 km
50 km
30 km
Option 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

10. 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?
10/51
17/52
11/26
11/50
13/50
Option 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
