Question

25% of 240 +?% of 360° = 20% of 570​

Answer 1

Answer:

Value of ? is 15 .

Step-by-step explanation:

25% of 240

= 25/100 *240

= 1/4 * 240

= 60

20% of 570

= 20/100 * 570

= 1/5 * 570

= 114

Let ? = x

60 + x% of 360 = 114

=> x/100 * 360 = 114 - 60

=> 36x/10 = 54

=> 36x = 540

=> x = 540/36

=> x = 15 .

Value of ? is 15 .
