In a number with at least two digits, the last number was removed. The resulting number was n smaller than ghe previous one.

BartSMP [9]

Answer:

The largest possible value of n is 11.

(A) is correct option.

Step-by-step explanation:

Given that,

The number with at least two digits,the last number was removed. The resulting number was n smaller than the previous one.

We need to find the largest possible value of n

Using given data,

The smallest number of two digit is 10.

Now, we removed last digit then we get 1 which is equal to 10 divided 10.

So, n = 10

But the largest number of two digit is 99.

We removed last digit then we get 9 which is equal to 99 divided 11.

So, n = 11

Hence, The largest possible value of n is 11.

(A) is correct option.

Alicia walks 4 miles in 1 hour and can speed walk 5 miles in 1 hour. What percent of Alicia's average speed walking rate is her

RSB [31]

Answer:

The % Alicia speed walking is 125 % of average walking

Step-by-step explanation:

Given as :

Distance cover by Alicia while walking = 4 miles

Time taken = 1 hour

So, Speed of Alicia while walking = $\frac{Distance}{Time}$

Or, S 1 = $\frac{4 miles}{1 hour}$

I.e S 1 = 4 mph

And

Distance cover by Alicia while speed walk = 5 miles

Time Taken = 1 hour

So, Speed of Alicia while speed walking = $\frac{Distance}{Time}$

Or, S 2 = $\frac{5 miles}{1 hour}$

I.e S 2 = 5 mph

Or, % Rate = $\frac{5}{4}$ ×100 = 125

Hence The % Alicia speed walking is 125 % of average walking Answer
