Option 1: 197.50
Option 2: 175.50
Option 3: 182.50
Option 4: 192.50
Correct Answer: 192.50
Solution : The cost price of almonds = INR 880 per kg Weight of packets sold = 200 gm Given that the weighing machine shows 400 gm when the actual weight is 350 gm. So, the weighing machine shows 200 gm when the actual weight is 175
Question : $\triangle$LMN is right angled at M. If $\angle$N = 45$^\circ$, what is the length of MN (in cm), if NL = 9$\sqrt2$cm?
Option 1: $9\sqrt2$
Option 2: $\frac{9}{\sqrt2}$
Option 3: $18$
Option 4: $9$
Correct Answer: $9$
Solution : $\triangle$LMN is right angled at M. $\angle$M = 90$^\circ$ $\angle$N = 45$^\circ$ $\angle$L = 180$^\circ$ – (45$^\circ$ + 90$^\circ$) = 45$^\circ$ So, $\triangle$LMN is an isosceles right-angled triangle. ⇒ LM = MN Also, NL = 9$\sqrt2$ cm Using the Pythagoras theorem, LM$^2$ + MN$^2$ =

Question : If $x$ men can do a piece of work in $x$ days, then the number of days in which $y$ men can do the same work is:
Option 1: $xy$ days
Option 2: $\frac{y^{2}}{x}$ days
Option 3: $\frac{x^{2}}{y}$ days
Option 4: $x^{2}y$ days
Correct Answer: $\frac{x^{2}}{y}$ days
Solution : Given: $x$ men can do a piece of work in $x$ days. We know the concept $M_1D_1=M_2D_2$, where $M_1$, $M_2$ are the persons and $D_1$, $D_2$ are the number of days. According to the question, ⇒ $x×x=y×D_2$ $\therefore D_2=\frac{x^{2}}{y}$ days Hence, the correct answer
