2.	The sum of digit of a two digit number is 12. the number obtained by inter changing the digit exceeds the given number by 18 .find the number
Answer» LET the TENS digit be x and the UNITS digit be y. So the number=10x+y A.q. x+y=12 x=12-y (equation 1) After interchanging the number we get =10y+x Also, (10y+x)-(10x+y)=18 10y+x-10x-y=18 9y-9x=18 9(y-x)=18 y-x=18/9 y-x=2 From eauation 1 x=12-y So, y-(12-y)=2 y-12+y=2 2y=12+2 2y=14 y=14/2 y=7 And x=12-y =12-7 =5 Hence the number is 57.

3.	The sum of a two digit no. and the no.formed by interchanging the digits is 132
Answer» Let the digits be a and B,where b is the unit number and a is the TENTH PLACE number.. so according to the given CONDITION (10a+b)+(10b+a) = 132 (11a+11b) = 132 a + b = 12....(1) so better find combinations of a and b such that their digit sum is 12.. as shown in eq (1) while we add the ORIGINAL two digit obtained number with the reversed number..the sum should b 132 ( given in the question) so the two digit number will be either 75 or 57

14.

there are 8 teachers in a school .when a 35 year old teacher was transfered and another teacher joined,the average age was increased 2 year .how old is t e new teacher?

Answer»

Average = (Total Quantity)/ Number of quantity

So,

Let the average AGE of teachers be x

Let y be the age of teacher that JOINED

So,

Total age of 8 teachers when 35 year old one did not LEAVE was,

=8x

When 35 year old leave and new one joined then,

Total sum of ages

= 8x -35 + y

Now,

The average of this increased by 2

SO,

(8x -35 + y)/8 = x + 2

8x -35 + y = 8x +16

-35 + y = 16

y = 35 +16

y=51

So,

A 51 year old teacher joined the SCHOOL

The cost of packaging of the oranges is 20% the cost of fresh oranges themselves. the cost of oranges increased by 30% but the cost of packaging decreased by 50%, then the percentage change of the cost of packed oranges, if the cost of packed oranges is equal to the sum of the cost of fresh oranges and cost of packaging
Answer» Answer: The percentage CHANGE of the cost of packed oranges is 16.6%. Step-by-step explanation: Given : The cost of packaging of the oranges is 20% the cost of FRESH oranges themselves. The cost of oranges increased by 30% but the cost of packaging DECREASED by 50%. To find : The percentage change of the cost of packed oranges, if the cost of packed oranges is equal to the sum of the cost of fresh oranges and cost of packaging? Solution : Let the cost of oranges be Rs.100. The cost of packaging of the oranges is 20% the cost of fresh oranges themselves. Packaging cost is $\frac{20}{100}\times 100=20$ Initial total cost = Cost of oranges + Packaging cost Initial total cost = 100 + 20 Initial total cost = Rs.120 The cost of oranges increased by 30% but the cost of packaging decreased by 50%. i.e. the cost of the oranges = $100+\frac{30}{100}\times 100=130$ The cost of packaging = $20-\frac{50}{100}\times 20=10$ Fresh total cost = 130+10=Rs.140. Increased cost = Fresh total cost - Initial total cost Increased cost = 140-120 Increased cost = 20 Percentage increased cost is $\frac{20}{120}\times 100= 16.6\%$ THEREFORE, The percentage change of the cost of packed oranges is 16.6%.

The cost of packaging of the oranges is 20% the cost of fresh oranges themselves. the cost of oranges increased by 30% but the cost of packaging decreased by 50%, then the percentage change of the cost of packed oranges, if the cost of packed oranges is equal to the sum of the cost of fresh oranges and cost of packaging

Answer»

Answer:

The percentage CHANGE of the cost of packed oranges is 16.6%.

Step-by-step explanation:

Given : The cost of packaging of the oranges is 20% the cost of FRESH oranges themselves. The cost of oranges increased by 30% but the cost of packaging DECREASED by 50%.

To find : The percentage change of the cost of packed oranges, if the cost of packed oranges is equal to the sum of the cost of fresh oranges and cost of packaging?

Solution :

Let the cost of oranges be Rs.100.

The cost of packaging of the oranges is 20% the cost of fresh oranges themselves.

Packaging cost is $\frac{20}{100}\times 100=20$

Initial total cost = Cost of oranges + Packaging cost

Initial total cost = 100 + 20

Initial total cost = Rs.120

The cost of oranges increased by 30% but the cost of packaging decreased by 50%.

i.e. the cost of the oranges = $100+\frac{30}{100}\times 100=130$

The cost of packaging = $20-\frac{50}{100}\times 20=10$

Fresh total cost = 130+10=Rs.140.

Increased cost = Fresh total cost - Initial total cost

Increased cost = 140-120

Increased cost = 20

Percentage increased cost is $\frac{20}{120}\times 100= 16.6\%$

THEREFORE, The percentage change of the cost of packed oranges is 16.6%.

P and Q are any two points lying on the sides DC and AD respectively of a parallelogram ABCD show that ar(ΔAPB)=ar Δ(BQC).

Answer»

If a parallelogram and a triangle are on the same base and between the same parallels then area of the triangle is half the area of the parallelogram.

==========================================================

Given: In parallelogram ABCD, P & Q any two POINTS lying on the sides DC and AD.

To show: ar (APB) = ar (BQC).

Proof:

Here, ΔAPB and ||gm ABCD stands on the same base AB and lie between same parallel AB and DC.

Therefore,

ar(ΔAPB) = 1/2 ar(||gm ABCD) — (i)

Similarly,

Parallelogram ABCD and ∆BQC stand on the same base BC and lie between the same parallel BC and AD.

ar(ΔBQC) = 1/2 ar(||gm ABCD) — (II)

From eq (i) and (ii),we have

ar(ΔAPB) = ar(ΔBQC)
