SQUARE OF NUMBERS ENDING WITH 5

TECHNIQUE

let's take a number 45

• first write 25.
• then multiply the number 4 with the immediate next number, i.e. 5, so, 4 x 5 = 20
• therefore the answer is 2025

Now let's take the number 85.

• the answer would be (8x9)25 =7225

Similarly we can find the square of the number 65

• the answer would be (6x7)25 =4225

Similarly we can find the square of the number 115

• the answer would be (11x12)25 =1322                                                                                     those who read this also read
