1.	37.If x is greater than or equal to 25 and y is lessthan or equal to 40, then which one of thefollowing is always correct?!(a)x is greater than y(b)(y - x) is greater than 15(c)(y-x) is less than or equal to 15(d)(x + y) is greater than or equal to 65
Answer» x is greater than y in this question x>=25 ---(i)y<=40 ---(ii) Multiplying (i) equation with (-1), we get-x<=-25 ---(iii) Adding (ii) and (iii), we gety-x <= 40-25 y-x <= 15 Option(c) is the correct answer.

Answer»

x is greater than y in this question

x>=25 ---(i)y<=40 ---(ii)

Multiplying (i) equation with (-1), we get-x<=-25 ---(iii)

Adding (ii) and (iii), we gety-x <= 40-25

y-x <= 15

Option(c) is the correct answer.
