Answer: Option A

Explanation:

According to the problem, 10 years ago, P was half of Q's age. So, the present age of P is 3x = 15 and the present age of Q is 4x = 20. Therefore, the total of their present ages = 15 + 20 = 35. Hence, the correct answer is option A (35).

Answer: Option C

Explanation:

Let the numbers be x, x + 2, x + 4, x + 6 and x + 8.

Then [x + (x + 2) + (x + 4) + (x + 6) + (x + 8) ] / 5 = 61.

or 5x + 20 = 305 or x = 57.

So, required difference = (57 + 8) - 57 = 8 .

Answer: Option C

Explanation:

ধরি, A এর আয় 5x এবং B এর আয় 4x। A এর ব্যায় 3y এবং B এর ব্যায় 2y

প্রশ্নমতে, 5x- 3y = 1600………..(1)

এবং 4x - 2y = 1600………………(2)

(1×2) - ( 2×3) হতে পাই

10x- 6y- 12x+6y=3200-4800

বা, -2x = -1600

বা,x = 800

অতএব, A এর আয় = 5×800=4000 টাকা।

Answer: Option A

Explanation:

Sum of 10 integer is 462. The average of first 4 number is 52 and the average of last 5 number is 38. What is the fifth number ?

Sum of first 4 number = 4 X 52 = 208
Sum of last 5 number = 5 X 38 = 190
So, sum of 9 number = (208 + 190) = 398

So, the 5th number = (462 - 398) = 64 (Ans:)

Answer: Option B

Explanation:

At 4:20, the minute hand is on the 4, and the hour hand is 20/60 = 1/3 of the way from the 4 to the 5. Since the numbers on the clock are 360/12 = 30 degrees apart, the smallest positive angle between the hands at 4:20 is 30(4 1/3 - 4) = 30(1/3) = 10 degrees.
