The value of a two-digit number is 10 more than 3 times the sum of its digits. The units digit is 1 more than twice the tens dig
mrs_skeptik [129]

Answer:

49

Step-by-step explanation:

the number is "ab" (2 digits).

ab - 10 = 3×(a+b)

a number is actually the sum of multiplying the digits with their associated powers of 10.

a×10 + b - 10 = 3a + 3b

7a - 2b = 10

b-1 = 2×a

b = 2a + 1

7a - 2×(2a+1) = 10

7a - 4a - 2 = 10

3a = 12

a = 4

b = 2×4 + 1 = 9

4) Let the number be : N

Given : 10% of this number is 25

\sf{\implies 10\% \ of \ N = 25}

\sf{\implies \dfrac{10}{100} \times N = 25}

\sf{\implies \dfrac{N}{10} = 25}

\sf{\implies N = 250}

Now we need to find 60% of 250

\sf{\implies \dfrac{60}{100} \times 250}

\sf{\implies 6 \times 25}

\sf{\implies 150}

5) Given : James left the home at 10 : 00 AM

First : He will meet his friend Tom at the skate park which is 15 minutes walk from his home.

So, James reached the skate park 10 : 15 AM

Second : They stayed at the skate park for an hour

So, till 11 : 15 AM James and Tom were at skate park

Third : Then they will take a 10 minutes walk over to the Burger bar

So, James and Tom reached the Burger bar at 11 : 25 AM

6) First let us find 75% of 80

\sf{\implies \dfrac{75}{100} \times 80}

\sf{\implies 15 \times 4}

\sf{\implies 60}

Now let us find 40% of 30

\sf{\implies \dfrac{40}{100} \times 30}

\sf{\implies 12}

Now, (60 - 12) = 48

<u>Answer:</u> 75% of 80 is 48 greater than 40% of 30

7) Given : Journey to school takes 70 minutes

We know that : 1 hour = 60 minutes

So, 70 minutes = 1 hour + 10 minutes

Given : Boy leaves the home at 0715

<u>Answer:</u> The Boy arrives at 0825
