Answer 1

Step-by-step explanation:

Q 1. (a) Write 275 in generalized form.

A 3 digit number madeup of digits a, b, c will be written as,

abc = 100 × a + 100 × b + 1 × c

hence generalised form of number

275 = 100×1 + 100×1 + 25×3

(b) Cost of 3 pens is ₹ 45. Find the cost of 5 such pens.

Cost of 3 pens = 45

Cost of 1 pens = 45/3 = 15

Cost of 5 pens = 15 × 5 = 75 ₹ answer
