Answer 1

5kg of tea of Rs .300 kg to be mix....

The total value of 240 Rs per Kg tea bag is Rs. 2400..

Consider the 'X' kg of the tea bags with Rs. 300/kg..

Now,

2400 + 300X / 10 +X = 260

2400+ 300X = 2600+260X

40X= 200

Therefore X=5

300 x 5 = 1500

You can cross-check the answer as

2400+1500/15=260.....

I just give you the idea you can solve it as per your textbook method.....
