Answer: Option C

Explanation:

0.25M + (1/5)M + 660 = M

Now, let's solve for M:

Combine like terms on the left side:

(0.25M + 0.2M) + 660 = M

(0.45M) + 660 = M

Now, isolate M on one side of the equation:

0.45M = M - 660

Subtract M from both sides:

0.45M - M = -660

-0.55M = -660

Now, divide both sides by -0.55 to find the value of M:

M = -660 / -0.55 M = 1200

So, the total amount of money they divided (M) is Tk. 1200.

Now, we need to find how much money Ishaq received, which is (1/5) of M:

Ishaq's share = (1/5) * 1200 Ishaq's share = 240

Ishaq received Tk. 240.

A. 60
B. 70
C. 75
D. 85
E. None of these

View Answer	Favorite Question

Answer: Option C

Explanation:

Total score for first 4 tests:
Average score (80) * Number of tests (4) = Total score
Total score = 80 * 4 = 320

Desired average after 7 tests:
Average score (85) * Number of tests (7) = Total desired score after 7 tests
Total desired score = 85 * 7 = 595

Minimum score needed on remaining tests:
Total desired score - Total score from first 4 tests = Score needed on remaining 3 tests
Score needed = 595 - 320 = 275

Minimum score for the 5th test:
Since Rashed can score a maximum of 100 on any test, we need to find the minimum score for the 5th test considering the remaining 2 tests can score a maximum of 100 each.
Score needed on remaining 3 tests - Maximum score possible on remaining 2 tests = Minimum score for 5th test
Minimum score = 275 - (100 + 100) = 275 - 200 = 75
