- Ratio of the number of apples eaten by A and B is 4:7. While ratio of the number of apples eaten by B and C is 5:3. If the number of apples eaten by C is 21. Find the number of apples eaten by A.
3525302015Option D

Number of apples eaten by A = 4/7*5/3*21 = 20 - Rita and Gita started a business together with an investment of Rs.800 and Rs.1000 resp. After a year, Rita added Rs.200 while Gita withdrew Rs.400. Find the profit share of Rita after 2 years, if total profit in 2 years was Rs.1700.
Rs.500Rs.800Rs.900Rs.700Rs.600Option C

Ratio of profit share = (800+800+200): (1000+1000-400) =9:8

Profit share of Rita = 9/17*1700 = Rs.900 - If Rs.1500 and Rs.1200 is deposited at 10% compound interest and 10% simple interest per annum. Find the difference between simple interest and compound interest earned after 2 years.
Rs.60Rs.75Rs.80Rs.64Rs.78Option B

CI = 1500*{(1.1)^2 – 1} = Rs.315

SI = 1200*0.1*2 = Rs.240

Difference = Rs.75 - Two articles A and B of cost prices Rs.400 and Rs.600 resp. have been sold for Rs.480 and Rs.640 resp. Find the overall profit percentage earned .
13%19%12%16%10%Option C

Total cost price = Rs.1000

Total Selling Price = Rs.1120

Profit% = [(1120-1000)/1000]*100 = 12% - If the time taken by a boat to travel 180 km upstream and 80 km downstream is 5 hours.Find the time taken by the boat to cover 126 km upstream and 56 km downstream.
5.5 hours3.5 hours4.9 hours2.2 hours1.5 hoursOption B

Let the upstream and downstream speed be x km/hr. and y km/hr. resp.

180/x + 180/y = 5

Multiply both sides by 7/10, we get

126/x + 56/y = 3.5

Time taken = 3.5 hours - 60*3 – 420/21 – 100 = ?
7060403050Option B

60*3 – 420/21 – 100 = ?

=>180 – 20 – 100 = ?

=>? = 60 - 10*5 + 50% of 200 – 12*10 = ?
4020501030Option E

10*5 + 50% of 200 – 12*10 = ?

=>50+ 100 – 120 = ?

=>? = 30 - 360 /12 + 40% of 400 – 6*5 = ?
144125160200175Option C

360 /12 + 40% of 400 – 6*5 = ?

=>30 + 160 – 30 = ?

=>? = 160 - 120*2 + 3*50 – 500 /25 = ?
300325370320355Option C

120*2 + 3*50 – 500 /25 = ?

=>240 + 150 – 20 = ?

=>? = 370 - 336/14 – 378/9 + 552/12 = ?
2212192820Option D

336/14 – 378/9 + 552/12 = ?

=>24 – 42 + 46 = ?

=>? = 28
