Answer 1

Answer:

i) 80 Strawberries, 1 Mango and 19 Apples.

II) 4

Step-by-step explanation:

Suppose we buy S number of strawberries, M number of Mangoes, and A number of Apples.  100 fruits can be bought total, thus -

S + M + A = 100 ——-(1)

And only Rs. 100 can be spent, thus total price,

S/40 + 3 × M + 5 × A = 100 ——-(2)

Putting S = 80 is equation (1) & (2) we get,

80 + M + A = 100

M + A = 20 ——-(3)

And 80/40 + 3 × M + 5 × A = 100

= 3 × M + 5 × A = 98 ——-(4)

Solving equations (3) & (4), we get, M = 1 and A = 19 i.e. 1 Mango and 19 Apples.

Thus, we need to buy -

80 Strawberries = Rs 2

1 Mango = Rs 3

19 Apples = Rs 95

Total of 80 + 1 + 19 = 100.

Fruits of price 2 + 3 + 95 = 100 Rupees.

2. If 1/2 of 5 is considered equal to 3

=> (1/2)*5 is considered equal to (1+2)*5/5 = 3

=> The result of (a/b)*c is considered equal to (a+b)*c/c and as multiplication of c/c will always lead to multiplication by 1 which is identity, so (a/b)*c = a+b

So (1/3)*10 should be considered equal to (1+3)*10/10 = (1+3) = 4
