If sum of the number of people in only B and the number of people common in both A and B is 63 and the number of people in B is twice the number of people in A, then the values of x and y are respectively.1. 15,4 2. 48,5 3. 51,7 4. 51,8
Answer» Correct option: 1 - 24, 2 - 51, 7 Explanation: 1. ATP Number of people in B is 10 more than A ∴ x + y + 5 + 11 = y + 5 + 15 + 10 + 10 x = 24. Number of people in only B = x = 24. 2. ATP x + y + 5 = 63 x + y = 58 .........(i) x + y + 5 + 11 = 2 (15 + y + 5 + 10) x + y + 16 = 60 + 2y 58 + 16 = 60 + 2y (from equation (i)) y = 7 ∴ x + 7 = 58. x = 51.

Answer»

Correct option: 1 - 24, 2 - 51, 7

Explanation:

1. ATP

Number of people in B is 10 more than A

∴ x + y + 5 + 11 = y + 5 + 15 + 10 + 10

x = 24.

Number of people in only B = x = 24.

2. ATP

x + y + 5 = 63

x + y = 58 .........(i)

x + y + 5 + 11 = 2 (15 + y + 5 + 10)

x + y + 16 = 60 + 2y

58 + 16 = 60 + 2y (from equation (i))

y = 7

∴ x + 7 = 58.

x = 51.
