Answer 1

Answer:

C. {6,7,8}

Given.

15 - 4x< x - 10

x belongs to {0,1,2,3,4,5,6,7,8,9}

SOLUTION

15-4x< x-10

15+10< x+4x ( by transposition)

25< 5x

x>25÷5

x>5

here x is greater than 5

therefore,

x = {6,7,8,.....}

but according to the given condition and the answerable options

x={ 6,7,8}

Hence the correct option is C
