**Directions(1-5):** What will be the approximate value of the following question.

- (34.98)^2 = ?^3 + (14.99)^2
910857Option B

(34.98)^2 = ?^3 + (14.99)^2

=> 35^2 = ?^3 + (15)^2

=> ?^3 = 1000

=> ? = 10 - 19.99% of 119.98 = ?^2 – 199.99% of 20
76859Option C

19.99% of 119.98 = ?^2 – 199.99% of 20

=> 20% of 120 = ?^2 – 200% of 20

=> ?^2 = 24+40

=> ? = 8 - 75% of 239.89 = ?^2 – (12)^2
1011151816Option D

75% of 239.89 = ?^2 – (12)^2

=> ?^2 – (12)^2 = 75% of 240

=> ?^2 – 144 = 180

=> ? = 18 - 49.98 * 11.98 = ?^2 + 0.24*95.98
2417161820Option A

49.98 * 11.98 = ?^2 + 0.24*95.98

=> 50*12 = ?^2 + 0.25*96

=> ?^2 = 600 – 24

=> ?^2 = 576

=> ? = 24 - 50% of 399.85 + 399.98% of 71 = ?^2
1920152214Option D

50% of 399.85 + 399.98% of 71 = ?^2

=> 50% of 400 + 400% of 71 = ?^2

=> ?^2 = 200+284

=> ? = 22 - The respective ratio of the present ages of father to son is 7:3. If five years ago, the ratio of their respective age was 5:2 then what will be the son’s age five years from now?
30 years10 years20 years60 years50 yearsOption E

Father’s age = (7x-5) years

Son’s age = (3x-5) years

(7x-5)/(3x-5) = 5/2

=> x = 15 years

Son’s age = 45 years

Son’s age five years from now = 45+5 = 50 years - Ram borrows a sum of Rs.30000 at 25% p.a. simple interest and then lends it to Raghu at 40% p.a. compound interest, compounded half-yearly. What will be the loss/gain of Ram after one year?
Rs.6300Rs.4100Rs.5100Rs.4400Rs.5700Option E

Interest on amount borrowed = 30000*0.25 = Rs.7500

Interest on amount lent = 30000*{(1+0.2)^2 – 1} = Rs.13200

Profit = 13200 – 7500 = Rs.5700 - If the numerator of a fraction is increased by 25% and the denominator is decreased by 50% then the fraction obtained is 2/5. What is the original fraction?
4/214/257/243/205/21Option B

Le the original fraction be x/y.

(x+0.25x)/(y-0.5y) = 2/5

=>x/y = 4/25 - Kind decided to distribute 1260 coins among his three sons A,B and C in the ratio of 23:4 resp. but mistakenly he distributed the coins in the ratio of 2:3:x resp. and thus C got 200 coins less than he was supposed to receive. Find the value of x.
42356Option B

Number of coins C was supposed to get = {4/(2+3+4)*1260} = 560

Coins received by C mistakenly = x/(2+3+x)*1260

Now, x/(2+3+x)*1260 = 560 – 200

=> x = 2 - A and B started a business together with initial investment of Rs.3200 and Rs.4800 resp. After 3 months, C joined them with an investment of Rs.4000. If after a year they received a total profit of Rs.4950. Find the profit share of B.
Rs.1950Rs.2160Rs.2200Rs.2000Rs.2250Option B

Ratio of profit share of A:B:C = 3200*12:4800*12:4000*12

= 16:24:15

Profit share of B = 24/(16+24+15)*4950 = Rs.2160
