**Directions(1-5):** What will come in place of question mark “?” in the following questions.

- (13)^2 – (4)^3 – √676 + 2 = (?)^2
8177908592Option A

(13)^2 – (4)^3 – √676 + 2 = (?)^2

=>(?) = 169 – 64 – 26 + 2

= 81 - 24.92% of 1504 + 44.88% of 804 = ?
690685711708735Option E

24.92% of 1504 + 44.88% of 804 = ?

= 25/100 × 1500 + 45/100 × 800

= 375 + 360 = 735 - 69.39 – 58.46 + 79.98 = ? + 76.92
1114161015Option B

69.39 – 58.46 + 79.98 = ? + 76.92

= 90.91–76.92 = 13.99 == 14 - 444 ÷ 12 × 28 – 724 + 112 = ?
180211192200199Option D

444 ÷ 12 × 28 – 724 + 112 = ?

= 1036 – 836 = 200 - 2405 ÷ 47.88 + 20.12 × 24.96 = ?
550485500515496Option A

2405 ÷ 47.88 + 20.12 × 24.96 = ?

Let, 2400/48 + 20×25

= 50 + 500

= 550 - Murali borrows Rs.3500 from a bank at SI. After 3 years he paid Rs.1500 to the bank and at the end of 5 yrs from the date of borrowing he paid Rs.2725 to the bank to settle the account. Find the rate of interest.
6%8%7%5%10%Option D

Total interest

= (interest on 3500 for 3 years)+(interest on 2000 for 2 years)

=> [3500×3×𝑅]/ 100 + [2000×2×𝑅]/ 100

= 1500 + 2725 – 3500

=> 105R + 40R = 725

=> R = 5% - Rajesh started a business with Rs.20,000 and his friend Shilpa joined him after 4 months with Rs.30,000. After 2 more months, Rajesh withdrew Rs.5,000 of his capital and 2 more months later, Shilpa brought in Rs.20,000 more. If they want to share their profits at the end of the year then find the ratio.
20:3321:3229:3221:3122:35Option B

Now,

(20000×6+15000×6):(30000×4+50000×4)

= (20×6+15×6):(30×4+50×4)

= (20×3+15×3):(30×2:50×2)

= 105:160 = 21:32 - The distance between two cities A and B is 330 km. A train starts from A at 8 a.m. and travels towards B at 60 km/hr. Another train starts from B at 9 a.m. and travels towards A at 75 km/hr. At what time will they meet?
8 a.m1 p.m11 a.m3 p.m12 p.mOption C

Total distance travelled => 330 = 60x + 75(x−1)

=> 12x + 15(x−1) = 66

=> 12x + 15x−15 = 66

=> 27x = 66 +15 = 81

=> 3x = 9

=> x = 3

Hence, the trains meet at 11 a.m. - If daily wages of a man is double to that of a woman, how many men should work for 25 days to earn Rs.14400? Given that wages for 40 women for 30 days are Rs.21600.
1510252016Option E

Wages of 1 man for 25 days

= [21600 × 2 × 25]/[ 40 × 30] Number of men = 14400/[( 21600 × 2 × 25)/40 × 30] = 16 - A box contains 30 electric bulbs, out of which 8 are defective. Four bulbs are chosen at random from this box. Find the probability that at least one of them is defective?
575/783573/789571/788574/783570/783Option D

Required Probability = 1 – 22C4/30C4

= 1 – 209/783

= 574/783
