17.	how many different integers can be expressed as the sum of three distinct numbers from the set {3 10 17 24 31 38 45 52}?
Answer» Firstly we have to find three such numbers whose sum can be one of the NUMBER from the SET. The question asked is how MANY such three numbers are present. From the given set it is EVIDENT that the minimum number that can be obtained from sum of three numbers is 30(3 + 10 + 17). SIMILARLY the maximum number obtained will be 135(38 + 45 + 52). So you can see the numbers are having a common difference of 7. Therefore total numbers equals to (135 - 30)/7 + 1 = 105/7 + 1 = 15+1 = 16 [Ans].

Firstly we have to find three such numbers whose sum can be one of the NUMBER from the SET.

36.	Find the solution of AA+BB+CC=ABC find the value of ABC
Answer» First focus on the answer ABC. Notice the largest result can be 99 + 88 + 77 = 264, so the answer has to be in the 200s or the 100s. This means A = 1 or 2. Next focus on the sum of the units digits. We know A + B + C = C (units), which means A + B = 0 (units). Therefore, we have A = 1 and B = 9 or A = 2 and B = 8. There are TWO possible cases: 11 + 99 + CC = 19C 22 + 88 + CC = 28C In the second case, we have 110 + CC = 28C. Focusing on the TENS column, we must have 1 + C = 8, which means C = 7. But then we end up with 110 + 77 = 187, which cannot work since we need a 2 in the hundreds place. This case does not yield a result. In the first case, we have 110 + CC = 19C. Focusing on the tens column, we must have 1 + C = 9, which means C = 8. We then have 110 + 88 = 198, and this works! The answer is 11 + 99 + 88 = 198.

Before finding it's perimeter. We have to find it's BREAD first. _____________________________ Now.. Area of rectangle = l × b => 12500 = 125 × b => b = $\dfrac{12500}{125}$ => b = 100 m ____________________________ Perimeter of rectangle = 2(l + b) => 2(125 + 100) => 2 × 225 => 450 m ___________________________ Perimeter of rectangle is 450 m ____________ [ $\bold{ANSWER}]$

40.

Area of a rectangular ground is 12500m^2.its length is 125 m.its parimeter is

Answer»

Area of a rectangular ground is 12500 m²

We know that area of RECTANGLE = L × b

Here..

l = length
b = breadth

length (l) = 125 m ______ [GIVEN]

We have to FIND it's PERIMETER.

Before finding it's perimeter. We have to find it's BREAD first.

_____________________________

Now..

Area of rectangle = l × b

=> 12500 = 125 × b

=> b = $\dfrac{12500}{125}$

=> b = 100 m

____________________________

Perimeter of rectangle = 2(l + b)

=> 2(125 + 100)

=> 2 × 225

=> 450 m

___________________________

Perimeter of rectangle is 450 m
