Question

Draw a circle with centre O and radius 3.5 cm. Locate a point of the circle such drawn from Q to the circle makes an angle of 30° with OQ with the help of following steps.Consider at the analytic figure as shown.Let OQ intersect the circle at A as shown and tangent from Q to the circle touch the circle at P then,a]What will be the measure of angle AOP? (b) Thus by drawing the central angle AOP , Pus located. Construct tangent at P and kocate Q.(c)measure OQ and relate it with OP.​

Answer 1

Answer:-

From the question,

Total cost of carpenting =Rs.6000

Rate of carpenting =Rs.50 per meter

Then,

Length of the carpet =(6000/50)=120m

∴ Area of the carpet =(120×(75/100))=90m

2

Area of the floor = Area of the carpet =90m

2

Hence, the width of the room = (Area / length)

=(90/15)

=6m

Marks given for one correct answer = 5

So, marks given for 10 correct answers

= 5 X 10 = 50

Radhika's score = 30

Marks obtained for incorrect answer

= 30- 50 = -20

Marks given for one incorrect answer

= (-2)

Therefore, number of incorrect answers

= (−20)÷(−2)=10.

hope it helps ♡
