The required natural smallest number which is divisible by both 3 and 4 is 444.
of a pole is in the mud. When of it is pulled out, on 8 metres long piece of the pole still remains in the mud. What is the total length of the pole?
Let the total length of the pole be x. Given, the total length of pole which is still in the mud = 8 m. If of it is pulled out, then remaining portion=1- = This 8 m is actually of the of the pole. so,
(A+B)’s one day work = (B+C)’s one day work = (C+A)’s one day work = (A+B+C)’s one day work = If A do work alone, then, A’s one day work = (A+B+C)’s one day work – (B+C)’s one day work 1/10 - 1/15 =(3-2)/30 =1/30 Thus, A can complete the work in = 30 days.
Let ones digit be x, then tens digit = Two-digit number = If 9 is added to the number, the digits are reversed. Therefore,
Factors of 65 = Factors of 117= Therefore,
Simplified value of ?
{(5.47-4.53)(5.47+4.53)/.94} - 2 10-2 = 8
let the depth of the lake be x m. Therefore, Thus, depth of the take is 3 m.
–350 m means 350 m below ground level. Therefore, Total distance to be covered by elevator
