   82
   88
   Option D
   +(1 2 + 5), +(2 2 + 10), +(3 2 + 15), +(4 2 + 20). . .
   46 + 36 = 82

   200
   222
   269
   250
   285
   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

    

4. 83, 124, 206, 370, 698, ?
   1354

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
