Q 3 - One year ago the ratio of Yamini?s and Gamini?s ages was 6 : 7 respectively. Four years hence this ratio would become 7 : 8. How old is Gamini?

### Answer : D

### Explanation

Let one year ago the ages of Yamini and Gamini be 6x and 7x years respectively. Therefore, present ages will be 6x + 1 and 7x + 1 years respectively. Now four years hence, (6x + 1 + 4) / (7x + 1 + 4) = 7/8 Or, (6x + 5) / (7x + 5) = 7/8 Or, 49x + 35 = 48x + 40 Or, X = 40 - 35 = 5 Hence Gamini's present age = 7x + 1 = 7*5 + 1 = 36 years

### Answer : D

### Explanation

Let man present age be x years. His age 15 year ago = (x-15) years. His age 15year hence = (x+15) years. (x+15) = 4(x-15) ⇒ 3x= 45 ⇒ x = 45

Q 6 - If the age of a mother is 3 times in the comparison of her daughter before the period of 10 year . 10 year later from the present date , the mother age would be 2 times of her daughter. In that situation what should be the age ratio of them at the present time?

### Answer : C

### Explanation

If the x year is the present age of her daughter. Mother age 10 year ago = 3(x-10) = (3x-30) year Present age of the mother = ( 3x-30+10) = (3x-20) year After 10 year age of the mother = (3x-20 +10) = (3x-10) year Son age after the period of 10 year = (x+10) year ∴ (3x-10) = 2(x+10) ⇒ x = 30 Mother present age = (3x-20) year = 70 years. Daughter present age = 30 years. Required ratio = 70: 30 = 7:3

Q 7 - The product of Ram age 5 year ago with his age 7 years later is 28 . What should be the present age of mr. Ram ?

### Answer : C

### Explanation

If present age of ram is x years. then (x-5)*(x+7) = 28 ⇒ x^{2}+2x-35 = 28 ⇒ x^{2}+2x-63 =0 ⇒ (x+9) (x-7) = 0 ⇒ x =7 ∴ 7 years is the present age of ram.

Q 8 - Before 6 year Radha got married . if we compare the marriage time with the present time , present time would be 5/4 times from the marriage time. At the present time son got 1/10 times in the comparison of his mother age . find out the present time age of his mother?

### Answer : B

### Explanation

Let radha age 6 year ago be x year. Then, radha present age = (x+6) years. ∴ x+ 6 = 5x/4 ⇒ 4(x+6) =5x = x =24 Present age of radha = (24+6) = 30 years. Son ?s present age = (1/10* 30) years = 3 years.

Q 9 - The sum of the ages of five girl born at the interval of 3 years each is 50 years. Find out the youngest girl age?
