Question : Wilting of plants occurs due to excessive :
Option 1: respiration
Option 2: guttation
Option 3: absorption
Option 4: transpiration
Correct Answer: transpiration
Solution : The correct option is transpiration.
Plant wilting is generally caused by excessive transpiration. Transpiration is the mechanism by which plants remove water vapour through tiny pores called stomata in their leaves. When transpiration rates surpass the plant's ability to absorb water from the soil via its roots, turgidity (the hardness of plant cells) is lost, resulting in wilting, in which the leaves and stems become limp and droop.

Question : What is the value of $\frac{1}{2}$ of $\frac{16}{5}+\frac{1}{8}$ of $\frac{24}{9} \times \frac{18}{12}-\frac{5}{8}$?
Option 1: $\frac{51}{40}$
Option 2: $\frac{68}{39}$
Option 3: $\frac{59}{40}$
Option 4: $\frac{61}{50}$
Correct Answer: $\frac{59}{40}$
Solution : Given: $\frac{1}{2}$ of $\frac{16}{5}+\frac{1}{8}$ of $\frac{24}{9} \times \frac{18}{12}-\frac{5}{8}$
= $\frac{8}{5}+\frac{1}{3}\times \frac{3}{2}-\frac{5}{8}$
= $\frac{8}{5}+\frac{1}{2}-\frac{5}{8}$
= $\frac{8}{5}+\frac{4-5}{8}$
= $\frac{8}{5}-\frac{1}{8}$
= $\frac{64-5}{40}$
= $\frac{59}{40}$
Hence, the correct answer is $\frac{59}{40}$.

5, 9, 13, 17, ?, 25
Option 1: 27
Option 2: 23
Option 3: 21
Option 4: 19
Correct Answer: 21
Solution : Given:
5, 9, 13, 17, ?, 25
In the given series, add 4 to the previous term to get the next term.
5 + 4 = 9; 9 + 4 = 13; 13 + 4 = 17; 17 + 4 = 21; 21 + 4 = 25
So, the missing number is 21. Hence, the third option is correct.

Question : A sum becomes Rs.15,500 in 7 years on simple interest at the rate of 30 percent per annum. What is the total interest for the 7 years?
Option 1: Rs. 12,200
Option 2: Rs. 1,47,000
Option 3: Rs. 10,500
Option 4: Rs. 11,500
Correct Answer: Rs. 10,500
Solution : Given, Sum= Rs. 15500
Rate of interest (r) = 30% per annum
Time (t) = 7 years
Let the principal be P.
⇒ [P + (simple interest)] = sum
⇒ [P + $\frac{\text{Prt}}{100}$] = sum
⇒ [P + $\frac{\text{P} × 30 × 7}{100}$] = 15500
⇒ [P + $\frac{\text{P} × 210}{100}$] = 15500
⇒ [P + $\frac{\text{21P}}{10}$] = 15500
⇒ $\frac{31\text{P}}{10}$ = 15500
⇒ P = $15500 × \frac{10}{31}$
⇒ P = 5000
Simple interest = 15500 – 5000 = Rs. 10500
Hence, the correct answer is Rs. 10500.
Question : The total cost of a dishwasher and a vacuum cleaner was INR 78,750. The vacuum cleaner was sold at a profit of 37% and the dishwasher at a loss of 23%. If the selling price was the same for both items, then the cost price of the cheaper item was:
Option 1: INR 51,375
Option 2: INR 29,375
Option 3: INR 30,750
Option 4: INR 28,335
Correct Answer: INR 28,335
Solution : Let the cost price of the dishwater and vacuum cleaner be INR $y$ and INR $x$, respectively.
Total cost price of a dishwasher and a vacuum cleaner = INR 78,750
$x$ + $y$ = $78750$-------------------(i)
Profit of vacuum cleaner = 37% of $x$ = $0.37x$
Selling price of vacuum cleaner = $x$ + $0.37x$ = $1.37x$
Also, the loss of dishwasher = 23% of $y$ = $0.23y$
So, selling price of dishwasher = $y$ – $0.23y$ = $0.77y$
Since both have the same selling price,
⇒ $1.37x = 0.77y$
From equation (i),
⇒ $1.37(78750-y) = 0.77y$
⇒ $2.14y =107887.5$
⇒ $y$ = INR $50414.7 $
So, $x=78750-y= 78750-50414.7=28335.3$ = INR 28,335 approx
⇒ Since the vacuum cleaner is less expensive than the dishwasher.
Hence, the correct answer is INR 28,335.
