290558 The quotient of x by y added ot the product of x and y is written as:

1

\frac{x}{y} + xy

2

\frac{y}{x} + xy

3

\frac{xy + y}{y}

4

290559 If 2x $^{1}$ y and 3xy $^{1}$ denote the length and breadth of a rectangle, the its area is:

1 6xy

2 6x

^{1}

y

^{1}

3 6x

^{1}

y

^{1}

4 x

^{1}

y

^{1}

Explanation:

6xy
C 6x $^{1}$ y $^{1}$
Area of the rectangle = Length × Breadth,
= 2x $^{1}$ y × 3xy $^{1}$
= 6x $^{1}$ y $^{1}$

290561 Directions: In the following questions, the Assertions (A) and Reason(s) (R) have been put forward. Read both the statements carefully and choose the correct alternative from the following:
Assertion (A): The rule, which gives the number of matchsticks required to make the matchstick pattern L, is 2n.
Reason (R): For n = 1, the number of matchsticks required = 2 × 1 = 2.

1 Both A and R are true and R is the correct explanation of A.

2 Both A and R are true but R is not the correct explanation of A.

3 A is true but R is false.

4 A is false but R is true.
