Ques:- The perimeter of a semi circle is 144 cm then the radius is?

Recent Answer : Added by Admin On 2022-09-29 17:59:35:

Perimeter of semi circular = πr+2r

Where r is radius , π = 22/7

πr+2r= 144 (given)

(22/7)r +2r = 144

22r+14r = 144*7 (multiply both sides by 7)

36r = 144*7

r= 144*7/36 = 28

radius =28 cm

Area =( 1/2)πr^2

Area=( 1/2 )*(22/7)*28*28

= 1232cm^2
Ans : area is 1232 cm^2

Ques:- X and Y start a business jointly. X invests Rs.16000 for 8 months and Y remains in the business for 4 months. Out of the total profit Y claims 2/7th share. How much money is contributed by Y?

Recent Answer : Added by Admin On 2022-09-29 18:33:42:

Let\: the\: total\: price \: be\: Rs. X\: then,

B= 2x/7 & A= \left ( x-2 \right )/7

So, A:B = 5x/7 : 2x/7 = 5 : 2

Let \: B’s \: capital\; be\: Rs.Y\: then\: \left ( 16000\ast 8 \right )/4y= 5/2

=> (16000\ast 8\ast 2)/(4\ast 5) = y

=> y = Rs. 12800
