Answer 1

7:5 ɪs ᴄᴏʀʀᴇᴄᴛ

Step-by-step explanation:

ɴᴏ ᴏғ ʙʟᴜᴇ ʙᴀʟʟs= 200-130=70

Answer 2

Ratio of blue balls to that of green = 7: 5

because total no.of balls are 200 .

so 80 ( red ) + 50 ( green ) = 130

ie , 200( total ball ) - 130 ( green and red ) = 70

balance 70 ball is Blue and green ball is 50 .

so their ratio = 7 : 5
