Option (c) 90

The diagonals bisect the angles making 45 each and the sum is 90

For square ABCD, angle BAC = angle ACD = 45°

angle BAC + angle ACD = 45° + 45° = 90°

angle BAC + angle ACD = 45° + 45° = 90°

My 3- digit number has a 4 in the hundreds place. it has a greater digit in the tens place than in the ones place. The sum of the digits is 6. what is my number?

let the 3 digit number be 4xy

4 + x + y = 6

or x+y=2

So there are 3 possibilities - (x,y) can be (2,0) or (1,1) or (0,2)

But, it is given that x > y

so (x, y) can be only (2,0)

Number is 420

or x+y=2

So there are 3 possibilities - (x,y) can be (2,0) or (1,1) or (0,2)

But, it is given that x > y

so (x, y) can be only (2,0)

Number is 420

x+y cannot be 2.cause it has been mentioned that the sum of these 2 numbers is 6 n not 2. so,4+x+y=10. i hope im right.

Anan, Jay is right. sum of the digits is 6. Therefore 4+x+y is 6.

You have taken x+y as 6, missed the digit 4

You have taken x+y as 6, missed the digit 4

115*125=14375

difference be 10 and square of larger no -1 and write 75 on last.

u can solve in 3 sec......

it should be relevant to 100(.. like 101,105,107,98,96,94.....and so on,any value near to 100)

115=100+15

125=100+25(now add cross values)

115+25=125+15=140(both side sum is equal)

115 +15

125 +25

----------------

140 keep 2 zeros along with 140 bcz its 100 place digits,so

140,00+(15*25)=14375
