  1. $220$
  2. $330$

  4. $320$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
$\Rightarrow$Total number of crates$=11$

$\Rightarrow$one crates contain$= 50$plates

$\Rightarrow$so total number plates=$11\times50=550$

$\Rightarrow$the broken part of plates is $\dfrac{2}{5}$

$\Rightarrow$so the number of plates$=550\times\dfrac{2}{5}=220$

$\Rightarrow$the number plats left intact$=550-220=330$

Three friends, Mala, Leela and Sheela, divided a box of apples weighing $15\dfrac{9}{10}$ kg equally between the three of them. How many kgs of apples did each get?

  1. $5\dfrac{3}{10} kg$
  2. $3\dfrac{3}{10} kg $
  3. $3\dfrac{9}{10} kg $
  4. $5\dfrac{9}{10} kg $
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Total weight of the apple $15\dfrac{9}{10}kg=\dfrac{(15\times10)+9}{10}=\dfrac{159}{10}$

There are three, they divide the apple equally between them

so one person will get the weight of apple $=\dfrac{159}{3\times10}=\dfrac{159}{30}=5\dfrac{3}{10}kg$

Write the quadrant in which the following point lie
$(5, -3)$

  1. $Q _4$
  2. $Q _3$
  3. $Q _2$
  4. $Q _1$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
First quadrant        X=positive    and  Y=positive

Second quadrant  X=negative   and  Y=positive

Third quadrant      X=negative    and  Y=negative

Fourth quadrant    X=positive     and  Y=negative

$ (5,-3)$ has $X=5$, positive and $Y=3$,negative

$\therefore$ The point lies in the fourth quadrant.
