Question

If Rs. 600 buy 15 bunches of feed, how many will Rs. 1280 rupees buy?

Answer 1

Hint:-Before solving this question, we must know about the unitary method.

Complete step-by-step answer:
UNITARY METHOD: The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.
So, we will use the unitary method for solving this question. This means that firstly, we will calculate the number of bunches of feed for Rs. 1 and then we will multiply the answer with 1280. To find how many bunches of feed will come for Rs. 1280.

So, we will follow the steps mentioned in the hint given above.\[\]
Rs. 600 = 15 bunches
Rs. 1 \[=\dfrac{15}{600}=\dfrac{1}{40}\]
So, Rs. 1280 \[=\dfrac{1280}{40}=32\]
Therefore, Rs. 1280 can buy 32 bunches of feed.

Note:-One must be very careful while doing the calculations as if there is any mistake in calculations, then, the answer would come out to be wrong.
Also, one must know how to solve such questions using the unitary method as they can come in handy.
