Answer 1

Answer:

(a)

(i) 2,61,510

(ii) 2,61,500

(b)

(i) 18,630

(ii) 18,600

(c)

(i) 3,26,030

(ii) 3,26,000

(d)

(i) 21,070

(ii) 21,100

Step-by-step explanation:

(a)    

(i) 441 × 593 = 2,61,513

                    ≈ 2,61,510

(ii) 441 × 593 = 2,61,513

                    ≈ 2,61,500

(b)

(i) 125 × 149 = 18,625

                    ≈ 18,630

(ii) 125 × 149 = 18,625

                    ≈ 18,600

(c)

(i) 675 × 483 = 3,26,025

                     ≈ 3,26,030

(ii) 675 × 483 = 3,26,025

                      ≈ 3,26,000

(d)

(i) 229 × 92 = 21,068

                   ≈ 21,070

(ii) 229 × 92 = 21,068

                    ≈ 21,100
