Question 1
Option 2 is the correct answer
y = x - 55/ x=255
Question 2:
Last option is the correct answer
n = b + 2/ b= 5
Explanation:
Question 1
The given information can be framed into the Mathematical form as given below:
No of cards = x
Cards given to brother = 55
Remaining cards = x - 55
Total number of cards = y
y = x - 55
Plug y = 200
200 = x - 55
20. + 55 = x
x = 255
y = x - 55/ x = 255
Question 2:
Total number of shirts bought
n = b + 2
Plug n = 7
7 = b + 2
7 - 2 = b
b = 5
n = b + 2/ b = 5
