Question

Find the cost of 1 whole number 1/2 metres of cloth at rupees 105 whole number 1/2 per metre ​

Answer 1

It’s simple 1/2 metre for 1 number cloth
Then 1/2 cloth has length of 1/2*1/2 = 1/4 metre

Now 1/2 metre’s price is 105 then 1/4 metre’s price is

=1/4/105*1/2
=0.25/105*0.5
=0.25/52.5
=0.0049 ~49.00

The answer is 49.00 rupees

You can either solve it like this
1/2 metres is equals to 0.5
1/4 metre is equals to 0.25

Therefore 1/2 metre costs rupees 105
Then 1/4 metre costs 105/2
= 52.5 rupees


After that
= 52 rupees for 0.5+0.2=0.7
How much for for 0.2

=0.2*52/0.7
=0.2857*52
=14.8564
= ( remove first digit of query)
= 48.565
~49

If you remove query of that 0.5 metre from this equation it will give you the answer of 49 rupees which is the answer of the main sum

Now mathematically both answers is correct but you can choose any of these
