To find the largest 4 digit number exactly divisible by 88,
We should divide the largest possible 4 digit number by 88, and if we get any remainder than subtract it from that largest number.
The largest possible 4 digit number is 9999
Now,
88) 9999 (113
88
_______
119
88
_______
319
264
_______
55
_______
Therefore, the largest 4 digit number exactly divisible by 88 is given by
9999 - 55 = 9944.
Let each literature text book cost be Rs. X
Then, cost of mathematics text book = Rs. (X + 2)
ATQ,
5X = 38 + 3(X + 2)
5X = 38 + 3X + 6
2X = 44
X = 22.
Therefore, cost of each literature text book = Rs. X = Rs. 22.
And that of masthematics = X + 2 = Rs. 24.
Let the larger number be p
Then, smaller number = 1/6 x p = p/6
Given difference between two numbers = 25
p - p/6 = 25
5p/6 = 25
5p = 150
p = 30
Then, p/6 = 30/6 = 5
Hence, larger number = 30 and smaller number = 5 which makes the difference = 25.
Let the number be 3p and 5p
ATQ,
8p = 2 x 48
p = 96/8
p = 12
The numbers are 36 and 60.
Hence, the product of the numbers = 36 x 60 = 2160.
Number = 271 x 96 + 0 = 26016
=> 95) 26016 (273
25935
--------
81
Required number = 81.
Let x and y be the two parts of 96.
x/7 = y/9 => x:y = 7:9
=> The smallest part is = 7/16 x 96 = 42.
Let the middle digit be x.
Then, 2x = 10 or x = 5. So, the number is either 253 or 352
Since the number increases on reversing the digits, so the hundred's digit is smaller than the unit's digit.
Hence, required number = 253.
Two painters can complete two rooms in two hours.So 18 rooms can be painted in 6 hrs by 6 painters
Let t be the usual time. If the usual rate is 1 unit, then the unusual rate is 6/7.
Balance by the distance,
1 x t = (6/7)(t + 30)
7t = 6(t + 30)
we get t as,
t = 180 minutes = 3 hrs.
Let the number be x. Then,
15x - x = 56
x = 4
In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
Herein the given sequence, 4, 2, 1, 0.5, 0.25, 0.125,...
Common Ratio r = 2/4 = 1/2 = 0.5/1 = 0.25/0.5 = 0.125/0.25 == 0.5.
