A tailor had a number of shirt pieces to cut from a roll of fabric. He cut each roll of equal length into 10 pieces. He cut at the rate of 45 cuts a minute. How many rolls would be cut in 24 minutes ?
Number of cuts made to cut a roll into 10 pieces = 9.
Therefore, Required number of rolls = (45 x 24)/9 = 120.
If the LCM and HCF of two numbers are equal, then the numbers must be
If LCM = HCF then, the two numbers are equal.
Khushi bought the bangles of equal number of Rs. 34 per piece, Rs. 42 per piece and Rs. 6 per piece. She spends total Rs. 1722 on all types of bangles. How many bangles did she buy of each type ?
Let number of bangles kushi purchase of each type = x

x = 1722/82 = 21.
In the given numbers, if in each number first digit is replaced by the third digit, second digit is replaced by the first digit and third digit is replaced by the second digit then which number will be the biggest ?
653 749 872 933 541
Largest number = 974
Therefore, the required number is 749.
If two line pa + b = 2 and 3a + b = 4 are parallel to each other, then what is the value of p ?
Given two lines are parallel
m1 = -p
The condition for the two lines to be parallel is m1=m2
p = 3
