Answer: Option C
Explanation:
ধরি, ভগ্নাংশটি = x/y
প্রশ্নমতে, x + 7 /y = 2............. (1)
x/y - 2 = 1........... (2)
(1) নং হতে পাই
x + 7 = 2y
x - 2y = - 7......... (3)
(2)নং হতে পাই, x = y - 2
x - y = - 2........ (4)
(3) - ( 4) = x - 2y = - 7
x - y = - 2
- y = - 5
y = 5
x - 2 × 5 = - 7
x = - 7 + 10
x = 3
ভগ্নাংশটি, x/y = 3/5.
