Question

Now, observe how use systematically. Do you think that it have to follow without using brackets? (D) 7 100 7 x (100 + 9) - 7x100 + 7 x 9 = 700 +63 = 1 (1) 102 x 103 = (100 + 2) X (100 + 3) (100 + 2) x 100+ (100 - 10,000 + 200 - 300 + 6 = 10,000+ 500+ 6 - 100 x 100 + 2 x 100 + 100 x 3 + 2x3 * 10,506 (iii) 17 x 109 - (10 + 7) 109 - 10 x 109 + 7 x 109 = 10 X (100 + 9) + 7 x (100+ 9) = 10 x 100+ 10 x 9 + 7 x 100 + 7 x 9 = 1000+ 90 + 700 + 63 = 1,790 +63 = 1,853​

Answer 1

Answer:

merchant had Rs 78,592 with her. She placed an order for purchasing 40 radio sets at Rs 1200 each. How much money will remain with her after the purchase?

Solutions:

Total money the merchant had = Rs 78592

Number of radio sets she placed an order for purchasing = 40 radio sets

Cost of each radio set = Rs 1200

So, cost of 40 radio sets = Rs 1200 × 40 = Rs 48000

Money left with the merchant = Rs 78592 – Rs 48000 = Rs 30592

Hence, money left with the merchant after purchasing radio sets is Rs 30592
