785 should be in place of 795. - A man deposited 65% of his salary in a scheme which offers simple interest at therate of 7% per annum. If the interest earned by him after 3 years is Rs. 5733. Find his salary.
Rs. 40000Rs. 39000Rs. 48000Rs. 42000Rs. 55000Option D

Let salary be Rs. X.

Amount deposited on scheme = Rs. 0.65x

Now, 0.65x*7*3/100 = 5733

=>x = Rs. 42000 - The age of Radha and Ravina is in the ratio of 12:13 resp. If Ritisha’s age is 23 years who is one year younger than Radha , find the age of Ravina.
32 years22 years26 years18 years20 yearsOption C

Age of Radha = 23 + 1 = 24 years

Age of Ravina = 13/12*24 = 26 years - The average run scored by a batsman in 14 innings is 42.5 runs. If the overall average runs scored by the batsman in 15 innings decreases by 0.5 runs when he played the 15th innings , find the runs scored by the batsman in the 15th inning.
35 runs33 runs21 runs30 runs25 runsOption A

Total runs scored by the batsman in 14th innings

= 42.5*14 = 595 runs

Total runs scored in 15th innings = 42*15 = 630 runs

Runs scored by batsman in 15th innings = 630 – 595 = 35 runs - A and B started a business with investment of Rs. 4800 and Rs. 6000 resp. If the total profit earned in business is Rs. 2025, find the profit share of A.
Rs. 600Rs. 800Rs. 900Rs. 700Rs. 500Option C

Ratio of profit shared between A and B = 4:5

Share of A = 4/9*2025 = Rs. 900 - The number of balls in bag A and bag B is in the ratio 7:6 resp. and the number of balls in bag B and bag C is in the ratio 2:3 resp. Find the number of balls in bag A, if the average number of balls in each bag is 22.
1521292318Option B

Ratio of the number of balls in A , B and C = 7:6:9

Now, 7x+6x+9x = 22*3

=> x = 3

Number of balls in bag A = 7x = 21
