Question

There are 102 teachers in a school of 3300 students find the ratio of the number of teachers to number of students

Answer 1

Answer:

There are more than one way to solve this problem.

1 kg = 1000 g (grams); and, if a / b = c / x, then ax = bc. Now, let’s use the variable X to name the money value of 700 grams of mutton.

And so we may rewrite the problem as: If 1000 g of mutton is 500 Rs, then 700 g of mutton is X Rs.

We can solve this problem in at least the following two ways:

Since 1000 g / 500 Gs = 700 g / X Gs >>>>> then 1000X = 500 x 700 >>>>> 1000X = 350000

>>>>> X = 350000 / 1000 >>>>> X = 350 Rs

Since 1000 g / 700 g = 500 Gs / X Gs >>>>> then 1000X = 700 x 500 >>>>> 1000X = 350000

>>>>> X = 350000 / 1000 >>>>> X = 350 Rs

Answer: 700 grams of mutton is 350 Rs.
