Answer 1

1) SOLUTION:-

Given:

The difference between two positive integers is 75 the ratio of these integers is 7:4.

To find:

The cost of each.

Explanation:

Assume the Integer be R.

We have, two Integer is 7R & 4R.

According to the question:

=) 7R - 4R = 75

=) 3R = 75

=) R= 75/3

=) R= 25

Hence,

1st Integer= 7R = 7×25 = 175

2nd integer= 4R= 4× 25 = 100.

2) Number of Rs. 5 coins = x

then, the money = 5x

number of Rs. 2 = 5x/8

then, the money = 2 * 5x/8

                           = 5x/4

According to the question,

=> 5x + 5x/4 = 1000

after taking L.C.M.,

=> 20x + 5x  = 4000

=> 25x          = 4000

=> x              = 4000/25

=> x              = 160

Therefore, Rs. 5 coins = x = 160 coins

                  Rs. 2 coins = 5x/4 = 5 * 160/8

                                                = 100 coins
