Answer 1

Answer:

Explanation:

The rate of tea is Rs 60 per kg and the rate of sugar is Rs 12 per kg.

Step-by-step explanation:

We are given that last year 1 kg of tea and 3 kg of sugar together cost Rs 96. This year, the rates of tea increased by  15% and that of sugar by 10%. So the amount of tea and sugar now cost Rs. 108.60.

Let the rate of tea be 'Rs x per kg' and the rate of sugar be 'Rs y per kg'.

The first condition states that last year 1 kg of tea and 3 kg of sugar together cost Rs 96, that is;

                             

                                 ------------ [Equation 1]

The second condition states that this year, the rates of tea increased by  15% and that of sugar by 10%. So the amount of tea and sugar now cost Rs. 108.60, that is;

So, this year rate of tea =  

                                      =  

Also, this year rate of sugar =  

                                             =  

Now, the equation so formed is;

                             

                             

                                  {taking 5 common from both sides}

                                  {using equation 1}

                             

                             

                             

                               

Now, putting value oy y in equation 1 we get;

                             

                               

So, the per kg rates of tea is Rs 60 per kg and that of sugar is Rs 12 per kg.
