Question : The table shows year-wise productions of four crops (in tons) in a village during 2018-2019 to 2021-2022.
The difference between the average production of wheat and the average production of pulses (in tons) over the year is:
Option 1: 380
Option 2: 360
Option 3: 370
Option 4: 350
Correct Answer: 380
Solution : The average production of wheat $=\frac{720+680+790+690}{4}=\frac{2880}{4}=720$ The average production of pulses $=\frac{410+380+320+250}{4}=\frac{1360}{4}=340$ Difference $=720-340=380$ So, the difference between the average production of wheat and the average production of pulses over the year is 380 tons. Hence, the correct answer is 380.
Question : In $\triangle {ABC}$, D is a point on BC such that $\angle {ADB}=2 \angle {DAC}, \angle {BAC}=70^{\circ}$ and $\angle {B}=56^{\circ}$. What is the measure of $\angle A D C$?
Option 1: $72^{\circ}$
Option 2: $54^{\circ}$
Option 3: $74^{\circ}$
Option 4: $81^{\circ}$
Correct Answer: $72^{\circ}$
Solution :
Let $\angle DAC = x$ $\angle ADB = 2x$ $\angle BAC = 70^\circ$ $\angle BAD = 70^\circ - x$ In $\triangle ABD $ $⇒56^\circ + 2x^\circ + 70^\circ - x = 180^\circ $ $⇒ x = 54^\circ$ $⇒2x = 108^\circ$ Now, By linear pair of

Question : Pipes A, B and C can fill a tank in 20, 30 and 60 hours, respectively. Pipes A, B and C are opened at 7 a.m., 8 a.m., and 9 a.m., respectively, on the same day. When will the tank be full?
Option 1: 4:40 p.m.
Option 2: 5:40 p.m.
Option 3: 6:20 p.m.

Question : Divide 37 into two parts so that 5 times of one part and 11 times of the second part are together 227.
Option 1: 15 and 22
Option 2: 20 and 17
Option 3: 25 and 12
Option 4: 30 and 7
Correct Answer: 30 and 7
Solution : Let the first part be $x$, then the second part becomes $(37-x)$. According to the question, $5x + 11(37-x) = 227$ or, $407 − 6x = 227$ or, $x = 30$ So, first part will be $x = 30$ and second part will
