4.	A man sold a radio at 10% gain.if he had bought it at 20% less and sold it for rs.10 more he would have gained 40% find the cp of radio.
Answer» Answer: The COST price of radio is Rs.500. Step-by-step explanation: GIVEN : A man SOLD a radio at 10% gain. If he had bought it at 20% less and sold it for Rs.10 more he would have gained 40%. To find : The cost price of radio ? Solution : Let x be the cost price of the goods. A man sold a radio at 10% gain. The SELLING price of goods is $SP=\frac{100+P\%}{100}\times CP$ $SP=\frac{100+10}{100}\times x$ $SP=\frac{110}{100}\times x$ $SP=1.1x$ He had bought it at 20% less. $CP=x-20\%\times x$ $CP=x-0.2x$ $CP=0.8x$ Sold it for Rs.10 more. SP=1.1x+10 The profit percentage formula is given by, $P\%=\frac{SP-CP}{CP}\times 100$ $40=\frac{1.1x+10-0.8x}{0.8x}\times 100$ $0.4=\frac{0.3x+10}{0.8x}$ $0.4\times 0.8x=0.3x+10$ $0.32x=0.3x+10$ $0.32x-0.3x=10$ $0.02x=10$ $x=\frac{10}{0.02}$ $x=500$ Therefore, The cost price of radio is Rs.500.

A man sold a radio at 10% gain.if he had bought it at 20% less and sold it for rs.10 more he would have gained 40% find the cp of radio.

Answer»

Answer:

The COST price of radio is Rs.500.

Step-by-step explanation:

GIVEN : A man SOLD a radio at 10% gain. If he had bought it at 20% less and sold it for Rs.10 more he would have gained 40%.

To find : The cost price of radio ?

Solution :

Let x be the cost price of the goods.

A man sold a radio at 10% gain.

The SELLING price of goods is

$SP=\frac{100+P\%}{100}\times CP$

$SP=\frac{100+10}{100}\times x$

$SP=\frac{110}{100}\times x$

$SP=1.1x$

He had bought it at 20% less.

$CP=x-20\%\times x$

$CP=x-0.2x$

$CP=0.8x$

Sold it for Rs.10 more.

SP=1.1x+10

The profit percentage formula is given by,

$P\%=\frac{SP-CP}{CP}\times 100$

$40=\frac{1.1x+10-0.8x}{0.8x}\times 100$

$0.4=\frac{0.3x+10}{0.8x}$

$0.4\times 0.8x=0.3x+10$

$0.32x=0.3x+10$

$0.32x-0.3x=10$

$0.02x=10$

$x=\frac{10}{0.02}$

$x=500$

Therefore, The cost price of radio is Rs.500.

12.	Friends please give the full solution
Answer» As we know that sum of all the angles in a triangle is equal to 180 degree Therefore, (x-40°) +(x-20°)+(½x-10°) = 180° 2x+½x-70 =180° 2½x= 180°+70° 5/2x=250° => x=100 Hence, the VALUE of x is 100 Then, the value of FIRST angle of the triangle will be (x-40)= (100-40)=60° the value of SECOND angle will be (x-20)= (100-20)=80° Similarly, the value of third angle will be (½x-10)=(50-10)=40° The angles of triangle MEASURES 60°,80°and 40° HOPE IT HELP YOU !!!

26.

Anyone please.......

Answer»

1. The sum of all the angles in a quadrilateral is 360 degree

Let the FOURTH angle be x

So, 110+82+68+x = 360

260+x=360

360-260=x

100 degree=x

2. A+D = 180 (co - INTERIOR angle property)

55+A=180

180-55=A

125=A

B+C=180 (co-interior angles)

70+C=180

180-70=C

110=C

3. The sum of measure all angles in a quadrilateral is 360 degree

Let the fourth angle be x

56+115+84+x=360

265+x=360

360-265=95 degree

In the last TWO questions I had some CONFUSION so I have not given their answers.
