Answer: Option B

Explanation:

(P + Q) × 4/100 = 8

P + Q = 200........ (1)

এখানে, P এর মান সবচেয়ে কম ( ধনাত্মক সংখ্যা) হলে, Q এর মান সবচেয়ে বড় হবে।

Q = 200 - 1 = 199

Answer: Option B

Explanation:

Let 4A = 6B = 1OC = k. Then, A = k/4, B = k/6, and C =k/10 .

A : B :C = k/4 : k/6 : k/10 = 15 : 10 : 6.

Hence, C's share (4650 * 6/31) = Tk, 900.

1698 . If 4 (A's capital) = 6 (B's capital)=10(C's capital), then out of a profit of TK. 4650, C will receive :

A. TK. 900
B. TK. 1550
C. TK. 2250

Answer: Option A

Explanation:

Let,

4A = 6B = 10C = x

Now, A = x/4 ; B = x/6 ; C = x/10

A : B : C = x/4 : x/6 : x/10

= x/4 × 60 : x/6 × 60 : x/10 × 60

= 15 : 10 : 6

Profit of C = 4650 × 6/15 + 10 + 6 = 900Tk.
