If (x + 1x) = 2, then find the value of (x3 + 1x3) ÷ (x18 + 1x18)
An error 2% in excess is made while measuring the side of a square. The percentage of error in the calculated area of the square is:
100 cm is read as 102 cm.
A1 = (100*100)Sq.cm
A2 = (102*102)Sq.cm
(A2 - A1) = 1022-1002 = (102 + 100) x (102 - 100) = 404 sq.cm.
Find the next number in the sequence?
28, 16, 28, 76, 274
Given number sequence is 28, 16, 28, 76, 274
Here the sequence follows a pattern that
28
28 x 0.5 + 2 = 14 + 2 = 16
16 x 1.5 + 4 = 24 + 4 = 28
28 x 2.5 + 6 = 70 + 6 = 76
76 x 3.5 + 8 = 266 + 8 = 274
274 x 4.5 + 10 = 1233 + 10 = 1243
Hence, the next number in the given number sequence is 1243.
