4A + AB / 100 = 10881/100
4A + (AB/100) = 108 + (81/100)
So,
4A = 108 and AB/100 = 81/100 => AB = 81
Hence
A=108/4=27 and by solving AB 81, B = 3
Thus A+B = 30

There is four digit number in aabb form and it is a perfect square. Find out the number.
Check your answer:-
Click here to See AnswerWe can expand aabb as
=> 1000a + 100a + 10b + b
= 1100a + 11b = 11(100a + b)
for 11(100a +b) to be a perfect square 100a + b should be a multiple of 11 where a and b both are integers and single digit numbers.
lets say 100a + b = 11y, here y should also be a perfect square (such that 11*11*y is a perfect square), i.e. 1, 4, 9, 16, 25, 36
If you try to solve this, where a and b are single digit integers and y is also a perfect square, you can see one possible values of a and b are 7 and 4, where y = 64.
Thus the number should be 7744, it is a perfect square of 88.

All the rivers are magical, moment a worshiper crosses a river with any number of flowers, it becomes double. (For eg 1 flower becomes 2 flowers, 2 become 4 and so on).
How many minimum number of flowers a worshiper needs 2 carry from beginning such that he offers equal number of flowers in all the three temples, and he is left with zero flowers at the end of fourth river.
Solve this ??

also we can say that after offering flowers at second temple he should be left with x/2 flowers.
similarly after offering flowers at first temple he should be left with (3x/2)/2 flowers.
Thus he should be carrying (x + 3x/4)/2 flowers initially, i.e. 7x/8 flowers initially.
For number of flowers to be integer, x =8, thus he must carry 7 flowers initially and offer 8 flowers at each temple.

There are 7 people numbered as 1 to 7.
The number denotes their height.
Arrange them in a line in such a manner so that the line appears in alternative of their heights, I.e. one short then long, again short then long.
The condition is that, if one by one member(remove 1, then 2, then 3) from the line is omitted, the order of their height remains alternative.
You are depositing Rs. 3 in First day and Rs. 3 in Second day in your account. And you are withdrawing Rs. 4 from your account in Third day. You do this repeatedly. When soon do you have Rs. 60?
Check your answer:-
Click here to See SolutionThus you would have reached Rs. 60 in (60/2)*3 = 90 days, but important thing to notice is that you are withdrawing Rs. 4 on every third day so your balance will reach Rs.60 mark earlier than that.
So, if we observe we will reach (60-6)=Rs.54 in (54/2)*3=81 days, and as you will deposit Rs.6 in next two days, you will reach Rs.60 in 83days.
For a TV (worth Rs. 50000), a showroom announced two discount schemes.
First scheme is 65% discount.
Second scheme is ‘Ten times 10% discount on price over and over’.
Which one do you choose and why?
Check your answer:-
Click here to See SolutionX – X*10/100 = 90X/100, final price is 9/10th of initial price.
Thus price after 10 times discount of 10% over and over will be X(9/10)^10 = 0.3486X.
While price after 65% discount will be 0.35X.
Thus it will be more beneficial to choose Second scheme.
