Question

In a national park, the ratio of lions to elephant was 4:7. When 5 elephants were shifted to the other national park, the ratio of lions to the elephants became 3 : 5. How many lions and elephants does the national park have now ?​

Answer 1

Answer:

here is your answer

Step-by-step explanation:

given, the ratios

4:7 at first,

then after 5 elephants were shifted

3:5

let the number of lions be 4x

and the number of elephants be 7x

now 5 elephants are shifted,

then now the number of elephants. =  7x-5

then,

4x/7x-5 = 3/5

5×4x = 3(7x -5)

20x = 21x - 15

20x - 21x = -15

-x = -15

x = 15

Therefore, no.of lions = 4x

= 4 × 15

= 60

Therefore, no.of elephants = 7x - 5

= 7(15) - 5

= 105 - 5

= 100
