If a quarter kilogram costs Rs.60 then how much will it cost for 150 grams?

Let's first find the cost of 1 gram:

Cost of 1/4 kg (250g) = Rs. 60

Cost of 1 gram = Rs. 60 / 250g = Rs. 0.24 per gram

Now, let's find the cost of 150g:

Cost of 150g = Rs. 0.24 per gram x 150g = Rs. 36

So, the correct answer is: 36
