First number is 5 for next number, 5×2 + 1 = 11 for next number, 11×2 +1 = 23 next, 23×2+1 = 47 next , 47×2 + 1 = 95 for getting next number continue the same sequence, 95×2 + 1 = 191Next number in the series is 191
Let us assume that the required two digit number be as 10x + y Now, as per given data, xy = 12 and (10x + y) + 36 = 10y + x on solving , (10x + y) + 36 = 10y + x 10x + y + 36 = 10y + x 10x –…
The formula to calculate average speed is, Average speed = Total distance / Total time distance travelled can be obtained by formula, distance = speed x time distance travelled by train = d1 = 50km/hr x 1hr = 50km distance travelled by taxi = d2 = 32km/hr x 0.5hr = 16km hence total distance travelled…
