A geostationary orbit is a circular orbit 35,786 kilometres above the Earth's equator and following the direction of the Earth's rotation. Communications satellites and weather satellites are often given geostationary orbits, so that the satellite antennas that communicate with them do not have to move to track them, but can be pointed permanently at the position in the sky where they stay.
The LCM of two numbers is 4 times of their HCF. The sum of LCM and HCF is 280. If one of the number is 224, then the other number is:
The sum of two numbers is 156 and their HCF is 26. Find how many such pairs can be formed.
The greatest number of four digits which when divided by 10, 12, 14 leave remainders 8, 10, 12 respectively is:
The ratio of two number is 6 : 5 and their HCF is 15. So find and their LCM?
Three boys runs around a circular track and takes 20 min, 25 min and 30 min respectively to complete the one round. When do they all come relatively to ...
Let N be the greatest number that will divide 82, 105, 128 leaving the same remainder in each case. Then sum of the digits in N is:
The HCF and LCM of two numbers, A and B, are 14 and 196, respectively. The difference between these two numbers is 28. Find their sum.
The greatest number of four digits which when divided by 10, 12, 14 leave remainders 5, 7, 9 respectively is:
