Step-by-step explanation:

Given Mr A went to a market to purchase 3 kg of sugar, 10 kg of wheat and 1 kg of salt. Ina shop near to Mr. A’s residence, these commodities are priced at Rs. 20, Rs. 10 and Rs. 8 per kg whereas in the local market these commodities are priced at Rs. 15, Rs. 8 and Rs. 6 per kg respectively. If cost of travelling to local market is Rs. 25, find the net savings of Mr. A using matrix multiplication.

So let the shop and local market be represented by S and L
S = 20
10
8
Also L = 15
8
6
Let M be the amount needed for Mr A, then
M = 3
10
1
Now the total cost he pays will be M’S
The difference between total price in 2 shops will be
M’S – M’L = M’(S – L)
= (3 10 1) ( 20 (15
10 - 8
8) 2)
= (3 10 1) ( 5
2
2)
= 15 + 20 + 2
= 37
Now the cost of travelling to local market costs Rs 25, net savings will be
= 37 – 25
= 12
