Question

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

Answer 1

Step-by-step explanation:

l:e =4:7

=> l =4e/7

l:(e-5)=3:5

5l =3(e-5)

5×(4e/7) = 3(e-5)

20e =21(e-5)

20e = 21e - 105

e =105

l = 60

lions 60, elephants =105
