Question

n a series of tests, Kiran scored (8x + 32), (2x + 5) and (x + 19). The sum

of the scores is 100 marks. Find Kiran’s score in all the test​

Answer 1

Answer:

(8x + 32) + (2x + 5) + (x + 19) = 100

11x + 56 = 100

11x = 100 - 56

11x = 44

x = 44/11

x = 4

• First test = 8x + 32 = 8(4) + 32 = 32 + 32 = 64
• Second test = 2x + 5 = 2(4) + 5 = 8 + 5 = 13
• Third test = x + 19 = 4 + 19 = 23

Answer 2

Answer:

(8x + 32) + (2x + 5) + (x + 19) = 100 11x + 56 = 100

11x = 100 - 56

11x = 44

x = 44/11

x = 4

First test = 8x + 32 = 8(4) + 32 = 32 + 32 = 64

Second test = 2x + 5 = 2(4) + 5 = 8 +

5 = 13 Third test = x + 19 = 4 + 19 = 23
