View all: BANGLADESH BANK BANKERS | WRITTEN QUESTION (MATH) SOLVE | 1986

Correct Answer: সংখ্যার দুইটি 840 ,280

Explanation:

ধরি, বড় সংখ্যাটি ‘x

ছোট সংখ্যাটি (১১২০ -x)

প্রশ্নমতে, x – (১১২০ – x) = x $\times$$\frac{2}{3}$

⇒2x-1120=$\frac{2x}{3}$

⇒6x-3360=2x

⇒4x=3360

so,x=840

বড় সংখ্যাটি =840

ছোট সংখ্যাটি=240
