C.P. of the item = ( 6750 ×100 )/75 = Rs 9000
So, Reqd. S.P. of the item = (9000 × 115)/100=Rs 10350

2. (1)
Length of the rectangle = 112/8 = 14 cm, so  perimeter= 44 cm,
Circumference= 132-44=88 cm,
R = (88 × 7 )/(2 ×22)  = 14cm

2/5  of the number=90

5. (3)
The largest angle of the quadrilateral (6 ×360)/(6+4+3+5) = 120 degrees
Smallest angle of the triangle = 120 × 1/4 = 30 degrees
If second largest angle of the triangle = (x + 10)
So 30+ x+ x+10 = 180 , x = 70 degrees
