Let the digits at unit place be y. Let the digits at ten's place be x.
Number = 10x + y
Sum of digits of the two digits number is four times that in the unit's place. => x + y = 4y => x = 4y - y => x = 3y ......(i).
If the digits are reversed the new number will be 54 less that the original number.
Number obtained by reversing the digits = 10y + x
Number obtained by reversing the digits = 10x + y - 54 => 10y + x = 10x + y - 54 => 54 = 10x + y - 10y - x => 54 = 9x - 9y => 54 = 9(x - y) => 54/9 = x - y => 6 = x - y .........(ii).
Putting the value of x from Eq (i). in Eq (ii). => 6 = x - y => 6 = 3y - y => 6 = 2y => y = 6/2 => y = 3
Putting the value of y in Eq (ii). => 6 = x - y => 6 = x - 3 => -x = -6 - 3 => -x = -9 => x = 9
So, Number = 10x + y => 10(9) + 3 => 90 + 3 => 93
Hence, the original number is 93.

Preeti Dabral 4 years, 6 months ago

To find the rational numbers between 1/2 and 3/4 let us first equate the denominators (1/2) (2/2) = 2/4 (3/4)(1/1)=3/4 Now we have 2/4 and 3/4 Now will multiply both the fractions Numerator and denominator by 10. We get 20/40 and 30/40 Hence will find rational numbers now between 20/40 and 30/40 The rational numbers are 21/40. 22/40, 23/40, 24/40,25/40,26/40 and so on.

MERITS 1) It added to the strength and resources of the British without requiring them to undertake the risk and expenses of the war.

2) It sealed for ever the chance for the rise of France in India by eliminating all foreign elements except the English from the courts of the princes.

DEMERITS 1) Since the money demanded from the princes by the British was out of proportion, it virtually brought an economic ruin to the states. This forced the states to cut down their own welfare measures.

2) The second defect of the system was that it crushed the initiative and responsibility of the Indian prince by making them dependent upon the British for the maintenance of law and order and for the protection of the territorial boundaries.

Kdrd Rounder 4 years, 6 months ago

The hare went back happy that he managed to save his life, and narrated the entire event to his fellow animals.

Kdrd Rounder 4 years, 6 months ago

The hare cleverly took him to a well full of water, and told the lion to look down into the well. The lion saw his own reflection in the well, and thought it was another lion. Getting angry, he jumped into the well and drowned.

Kdrd Rounder 4 years, 6 months ago

One day, it was the hare’s turn to go into the lion’s den. He didn’t want to die! So, to save his life, he quickly came up with a plan. The hare entered the lion’s den a little late, and when the lion asked him the reason for being late, he told him that there was another lion in the jungle, who was claiming to be the king of the jungle. Hearing this, the lion got angry and demanded to see the other lion.

Kdrd Rounder 4 years, 6 months ago

One day, the animals of the jungle decided to find a way out, and called for a meeting. All the animals of the jungle, including the lion, were present for the meeting. One of the animals then put forward a proposal for the lion. They asked the lion to stop hunting down the animals in the forest, and in return, they would send one animal a day to his den, where he could kill the animal and eat it as his food. The lion agreed, but placed a condition. If the animal did not reach his den in time, he would hunt down each animal of the jungle. The animals agreed to this condition.

Kdrd Rounder 4 years, 6 months ago

Once upon a time, there lived a lion in the jungle. He was very powerful and strong, and all the animals of the jungle feared him. The lion used to dominate and kill other animals in the jungle for his food, and sometimes, even unnecessarily.
