Solution
Cost of 1 VCR set = Rs 24350
Cost of 139 VCR sets = 139 × 24350
=24350 × (140 − 1) (Using distributive property)
=24350 × 140 − 24350
=3409000 − 24350
= Rs. 3384650
∴ The cost of all the VCR sets is Rs 33,84,650.
Cost of 139 VCR sets = 139 × 24350
=24350 × (140 − 1) (Using distributive property)
=24350 × 140 − 24350
=3409000 − 24350
= Rs. 3384650
∴ The cost of all the VCR sets is Rs 33,84,650.
