Explanation

the greatest number is 9,86,54,210. We arrange the given digits in ascending order to form the smallest number. Hence, the smallest number is 1,02,45,689.

Formation of Greatest and Smallest Numbers.

To Form the Greatest Number To Form the Smallest Number

The smallest digit in the ones place that is 3. The next smallest digit in the ones place that is 9.

Explanation

Tap X can fill the tank in 10 hours, which means it fills 1/10 of the tank per hour.

Tap Y can fill the tank in 15 hours, which means it fills 1/15 of the tank per hour.

When both taps are opened together, their combined rate of filling the tank is the sum of their individual rates:

(1/10 + 1/15) of the tank per hour

To add these fractions, we need a common denominator, which is 30. So we get:

(3/30 + 2/30) = 5/30 = 1/6 of the tank per hour

Since they fill 1/6 of the tank per hour together, they will fill the entire tank in 6

hours.

Explanation

Average = (12 + 15 + 18) ÷ 3 = 45 ÷ 3 = 15

Explanation

We see that 32 + 8 = 40 and 32 – 8 = 24. Now let us check this rule for one more term. We see that 16 + 8 = 24. Therefore this works for more than half of the given numbers. Hence the rule is correct. Therefore the missing number in the series is 16 – 8 =  8. The answer is  8.

Explanation

Let the S.P = 100

then C.P. = 25

Profit = 75

Profit% = 75/25 * 100 = 300%

Explanation

Suppose Imran has x rupees

If he gain 20 percent profit

After one year rupees = X + 20% of X

X + 20X/ 100 = 110X + 20X / 100

120X/100

Now if he has lost 25% on 120X / 100 then

Rupees after seconds year

= 120X/100 – 25% of 120 X/100

=120X/100 – 25(120X)/10000

= 1200X-3000X/10000

= 1200X-3000X/10000

= 9000X/10000

=9X/10=90X/100=90% OF X

Total lost = 100 – 90 =10

X = 10 % of X

Explanation

Since you are 5th in a queue starting from either end  so there are 2 persons to your left and 2 to your right

∴∴ Total number of persons are

5+2+2= 9
