Question
A circlular wire of radius 56 cm is bent in the form of
a rectangle whose sides are in the ratio of 13 : 9. The smaller side of the rectangle isSolution
Perimeter of rectangle = Circumference of circular wire 2(a + b) = 2πr 2(9x + 13x ) = 2 × 22/7 × 56 2× 22x = 2 × 22/7 × 56 x = 8 cm. Smaller side = 9 × 8 = 72 cm.
40% of 50 + 50% of ? = 25% of 300 - 10% of 250
140% of 1270 + 60% of 2085 = 1881 + β?β% of 287
48 Γ· 6 Γ β25 + 13 Γ 8 = ?
