? = 5068 x 4/37
? = 548
In the following question, by using which mathematical operator will the expression become correct?
18 ? 6 ? 9 ? 27
In the following question, correct the equation by interchanging two signs.
6 + 8 ÷ 4 – 4 = 8
In a group of buffaloes and ducks the number of legs are 24 more than twice the number of heads. What is the number of buffaloes in the group?
Let the number of buffaloes be x and number of ducks be y.
Now, number of heads = x + y
Number of legs = 4x + 2y .......(1)
But given that legs = 2(x + y) + 24 ......(2)
solving (1) & (2),we get
4x + 2y = 2x + 2y + 24
> x = 12.
Therefore number of buffaloes =12
The following equation is incorrect. Which two signs should be interchanged to correct the equation? 15 x 12 + 40 ÷ 40  6 = 21
If "–" means "added to", "+" means "divided by", "÷" means "multiplied by", "x" means "subtracted from", then 13 + 12 x 9 ÷ 3 – 6 = ?
If '+' means subtraction, '÷' means addition, '<' means multiplication and '>' means division, then find the value of the given statement,
The value of 9 ÷ 7 < 8 > (4>2) + 5 will be
In an algebraic expression, like terms are terms that contain the same variables raised to the same powers. Calculating xsquared plus xsquared is a matter of combining like terms.
Now x^{2} + x^{2} = 2x^{2}
Hence, xsquared plus xsquared is equal to 2 times x squared.
If "÷" denotes "multiplied by", "+" denotes "subtracted from", "–" denotes "added to" and "x" denotes "divided by", then which of the following equation is true?
Find out the two signs to be interchanged for making following equation correct
5 + 3 x 8  12 / 4 =3
On interchanging  and /, we get the equation as
5 + 3 x 8 / 12  4 = 3
or 5 + 3 x (2/3)  4 = 3
or 3 = 3, which is true.
