How many Palindrone number are there between 5000 To 67000 . Palindrone no 5335 is palindone no because if u read from first and last the value remains same
A456
B620
C630
D768
Answer: Option B
Explanation:5000 To 10000 = Per section 10 Total 5 section S/T = 5*10 = 50
Than
10000 To 67000 = Per Section 10 Total 57 Section S/T = 57*100 = 570
Total is = 50+570 = 620

How many 4-digit numbers contain no.2?
A3168
B3318
C3167
DNone of these
Answer: Option A
Explanation:Total number of four digit numbers =9000 (i.e 1000 to 9999 ) We try to find the number of numbers not having digit 2 in them.
Now consider the units place it can be selected in 9 ways (i.e 0,1,3,4,5,6,7,8,9) Tens place it can be selected in 9 ways (i.e 0,1,3,4,5,6,7,8,9)
Hundreds place it can be selected in 9 ways (i.e 0,1,3,4,5,6,7,8,9)
Thousands place can be selected in 8 ways (i.e 1,3,4,5,6,7,8,9) here '0' cannot be taken Total number of numbers not having digit 2 in it =9 x 9 x 9 x 8 =5832
Total number of numbers having digit 2 in it = 9000-5832 =3168

If twenty four men and sixteen women work on a day, the total wages to be paid is 11,600. If twelve men and thirty seven women work on a day, the total wages to be paid remains the same. What is the wages paid to a man for a day's work?
A200
B342
C250
D255
Answer: Option A
Explanation:Let man daily wages and woman daily wages be M and W respectively 24M+16W=11600
12M+37W=11600
By, solving the above equations gives M=350 and W=200

A manufacturer of chocolates makes 6 different flavors of chocolates. The chocolates are sold in boxes of 10.
How many "different" boxes of chocolates can be made?
A2003
B3003
C1231
D3013
Answer: Option B
Explanation:If n similar articles are to be distributed to r persons, x1+x2+x3......xr=n each person is eligible to take any number of articles then the total ways are n+r?1Cr?1
In this case x1+x2+x3......x6=10
In such a case the formula for non negative integral solutions is n+r?1Cr?1 Here n = 6 and r = 10. So total ways are 10+6?1C6?1 = 3003

A circle circumscribes three unit circles that touch each other. What is the area of the larger circle? Note that p is the ratio of the circumference to the diameter of a circle (3.14159265).
A3.14*(7+43?3)
B3.14*(7+3?3)
C3.14*(5+43?3)
DNone of these
Answer: Option A
Explanation:By joining centers of 3 unit circles we will get an equilateral triangle of length 2 unit. We have to find the length of the orange line.
And center of the equilateral triangle will be the center of the big circle.
So radius of the big circle will be = (1 + Circum radius of the equilateral triagle)
Formula for Circul radius of the equilateral triangle = 23*(3?2a) here 3?2a is the height of the triangle. a is the side of the triangle
Circum radius of equilateral triangle = 23*3?2*2=23?
Area of big circle will be =?r2=3.14*(1+23?)2 = 3.14*(1+43?+43) =3.14*(1+43?+43) = 3.14*(73+43?)
=3.14*(7+43?3)

The length, breadth and height of a room are in the ratio 3:2:1. If the breadth and height are halved, while the length is doubled. Then the total area of the 4 walls of the room will be decreased by
A30%
B18.75%
C15%
D13.50%
Answer: Option A
Explanation:Given l:b:h=3:2:1
let h=10, b = 20, and l = 30 area = 2(l+b)h
area= 2*(3x+2x)*x = 2(30+20)10=1000
Now after those adjustments in the measurements, l=60, b=10, h=5
area= 2(l+b)h = 2(60+10)5=700
Percentage decrease= 1000?7001000 * 1000=30%

Four people each roll a four die once. Find the probability that at least two people will roll the same number?
A5/18
B13/18
C1295/1296
DNone of these
Answer: Option B
Explanation:The number of ways of rolling a dice where no two numbers probability that no one rolls the same number = 6 * 5 * 4 * 3
Now total possibilities of rolling a dice = 64
The probability that a no one gets the same number = 6*5*4*364 = 518
So, the probability that at least two people gets same number = (1?518) = 1318
