Question
The perimeter of 3 squares is 18 cm, 27 cm and 36 cm
respectively. What will be the area of the square having perimeter equal to sum of edges of 3 squares? (in sq.cm)Solution
Let side of 3 squares be a, b and c cm respectively. => a = 18/3 = 6 cm => b = 27/3 = 9 cm => c = 36/3 = 12 cm Perimeter of new square = a + b + c = 27 => side = 27/3 = 9 cm Required area = side2 = 92 = 81 cm2.
(122 - 82 ) of 52 + 52 = ?2Â
A man purchases some pens at a rate of 4 for ₹14 and an equal number at a rate of 5 for ₹18. He sells all the pens at a rate of 6 for ₹20. What is...
20 * 8 + 40% of 100 + 60% of 150 = ?
What will come in the place of question mark (?) in the given expression?
(3.2 × 35 + ?) ÷ √16 = 38.5
(2197)1/3 + (18)2 − 121 = ? − 69 × 5
45% of 360 - 160 + ? = √324
52% of 400 + √(?) = 60% of 600 - 25% of 400
4387897 – 3286871 – 51926 = ?
26 2 – 13% of 400 + (529 ÷ 23 2 ) = ? 2Â
