Which of the following is not an integer?1). [(3.75 – 2.25) × 2]2). [(1.42 + 2.08) × 3]3). [(2.68 – 0.18) × 4]4). [(1.42 + 3.38) × 5]

Answer»

Solving the EXPRESSIONS,

⇒ [(3.75 – 2.25) × 2] = 3

⇒ [(1.42 + 2.08) × 3] = 10.5

⇒ [(2.68 – 0.18) × 4] = 10

⇒ [(1.42 + 3.38) × 5] = 24

∴ 10.5 is not an integer, as DECIMALS are not INTEGERS
