Question 3 Problems on Simultaneous Linear Equations Exercise 6

A 700 gm dry fruit pack costs Rs. 216. It contains some almonds and the rest cashew kernel. If

almonds cost Rs. 288 ‘per kg and cashew kernel cost Rs. 336 per kg, what are the quantities of the

two dry fruits separately?

Answer:

Given,

Cost of 700 gm of fruit = Rs 216

Cost of almonds = Rs 288 per kg

And the cost of cashew = Rs 336 per kg

Now, let the weight of almond = x gm and

The weight of cashew = (700 - x) gm

Then according to the conditions given in the problem, we have

288x + 235200 – 336x = 216000

288x – 336x = 216000 – 235200

x = -19200/-48 = 400

Therefore, the weight of almond = 400 gm and the weight of cashew = (700 – 400) gm = 300 gm
