1. The ratio between the present ages of Paresh and Suresh is 6:7. If Suresh is 4 years old than Paresh, what will be the ratio of the ages of Paresh and Suesh after 4 years ?
D. None of these
2. The ratio between the present ages of Paresh and Suresh is 5:7 respectively. If the difference between Suresh’s present age and Paresh’s age after 6 years is 2,what is the total of Paresh’s and Suresh’s present ages ?
A. 48 years
B. 52 years
C. 56 years
D. Cannot be determined
Let Paresh’s age and Suresh’s age be 6x years and 7x years respectively.
Then, 7x-6x = 4, so x = 4. Required ratio = (6x + 4) : (7x + 4)=28 : 32 =7: 8 which is not given in the options.
Let the present ages of Paresh and Suresh be 5x years and 7x years respectively.
Then,7x -(5x +6)=2 so, 2x =8 so, x=4. Required sum =5x +7x =12x =48 years.
