Sarika bought a camera and case for Tk. 120. If the camera cost Tk. 100 more than the case, how much did the camera cost ?
Correct Answer: Option B
Solution:
দেওয়া আছে, Camera ও Case এর দাম একত্রে 120 টাকা ।
ধরি, Case এর দাম x টাকা
Camera এর দাম (x + 100) টাকা
(x + 100) + x = 120 => 2x = 20 x = 10
অর্থাৎ Case এর দাম = 10 + 100 = 110 টাকা ।
