The present age of Sita's father is three times of Sita's present age. After 6 years the sum their age will be 69. Find their pr

Papessa [141]

Age of Sita is 14.25 years and her father is 42.75 years

Step-by-step explanation:

Step 1: From given details, let present age of Sita be x and that of her father be 3x.
Step 2: Form equations based on their ages in 6 years. (Given sum is 69)

⇒ (x + 6) + (3x + 6) = 69

⇒ 4x + 12 = 69

⇒ 4x = 57

⇒ x = 14.25

Step 3: Calculate age of Sita's father

⇒ 3x = 42.75

Answer:

There are 2450 ways.

Step-by-step explanation:

We can pick first the 4 man, and then the 4 women. The configuration of men and women are independant with each other, so the total of possibilities is obtained by multiplying the total possibilities to pick 4 men and the total possibilities of picking 4 women.

To pick 4 men from a group of 8, the total number of possibilities is the amount of ways to pick 4 elements from a group of 8. This number is represented by the combinatorial number of 8 with 4

${8 \choose 4} = \frac{8!}{4!4!} = 70$

To pick 4 women from a group of 7, we need to count the total amount of ways to pick 4 elements from a group of 7. This is the combinatorial number of 8 with 7

${7 \choose 4} = \frac{7!}{4!3!} = 35$
