Question : A shopkeeper gives an additional concession of 5% on an item which is already discounted by 15% on the marked price. If the buyer pays INR 3,068.50 for the item, then find the marked price.

Option 1: INR 3,500

Option 2: INR 3,700

Option 3: INR 3,800

Option 4: INR 3,780

Team Careers360 25th Jan, 2024

Correct Answer: INR 3,800


Solution : We know the formula for successive discounts,
Selling price = $MP(1 - \frac{D_1}{100})(1 - \frac{D_2}{100})$
Where $MP$ is the marked price and $D_1, D_2$ are the discounts.
$\mathrm{D_1=5}$%
$\mathrm{D_2=15}$%
On substituting the values,
$\mathrm{MP(1 - \frac{5}{100})(1 - \frac{15}{100})}=3068.50$
$⇒\mathrm{MP×( \frac{19}{20})×(\frac{17}{20})}=3068.50$
$⇒\mathrm{MP×( \frac{323}{400})}=3068.50$
$⇒\mathrm{MP}=\frac{400}{323}× 3068.50$

Question : A boat goes 10 km upstream in 50 minutes and the speed of the stream is 3 kmph. Find the speed of the boat in still water (in kmph).

Option 1: 15

Option 2: 10

Option 3: 8

Option 4: 12

Team Careers360 24th Jan, 2024

Correct Answer: 15


Solution : Given: A boat goes 10 km upstream in 50 minutes.
The speed of the stream is 3 kmph.
Upstream speed in km/h = $\frac{10}{50}×60=12$ kmph
Let the speed of a boat in still water be $x$ kmph.
We know that,
Upstream speed = speed of

Question : If the areas of two similar triangles are in the ratio 36 : 121, then what is the ratio of their corresponding sides?

Option 1: 6 : 11

Option 2: 11 : 5

Option 3: 6 : 5

Option 4: 5 : 12

Team Careers360 24th Jan, 2024

Question : The value of the expression $\sin^{2}1^{\circ}+\sin^{2}11^{\circ}+\sin^{2}21^{\circ}+\sin^{2}31^{\circ}+\sin^{2}41^{\circ}+\sin^{2}45^{\circ}+\sin^{2}49^{\circ}+\sin^{2}59^{\circ}+\sin^{2}69^{\circ}+\sin^{2}79^{\circ}+\sin^{2}89^{\circ}$ is:

Option 1: $0$

Option 2: $5\frac{1}{2}$

Option 3: $5$

Option 4: $4\frac{1}{2}$

Team Careers360 25th Jan, 2024

Correct Answer: $5\frac{1}{2}$


Solution : $\sin^{2}1^{\circ}+\sin^{2}11^{\circ}+\sin^{2}21^{\circ}+\sin^{2}31^{\circ}+\sin^{2}41^{\circ}+\sin^{2}45^{\circ}+\sin^{2}49^{\circ}+\sin^{2}59^{\circ}+\sin^{2}69^{\circ}+\sin^{2}79^{\circ}+\sin^{2}89^{\circ}$
Using the identity $\sin(90^{\circ} - \theta) = \cos\theta$, we get,
$\sin^{2}49^{\circ}=\sin^{2}(90^\circ-41^{\circ}) = \cos^2{41}^\circ$
$\sin^{2}59^{\circ}=\sin^{2}(90^\circ-31^{\circ}) = \cos^2{31}^\circ$
$\sin^{2}69^{\circ}=\sin^{2}(90^\circ-21^{\circ}) = \cos^2{21}^\circ$
$\sin^{2}79^{\circ}=\sin^{2}(90^\circ-11^{\circ}) = \cos^2{11}^\circ$
$\sin^{2}89^{\circ}=\sin^{2}(90^\circ-1^{\circ}) = \cos^2{1}^\circ$
$=\sin^{2}1^{\circ}+\sin^{2}11^{\circ}+\sin^{2}21^{\circ}+\sin^{2}31^{\circ}+\sin^{2}41^{\circ}+\sin^{2}45^{\circ}+\cos^{2}41^{\circ}+\cos^{2}31^{\circ}+\cos^{2}21^{\circ}+\cos^{2}11^{\circ}+\cos^{2}1^{\circ}$Each pair adds up to $1$ because $\sin^{2}\theta + \cos^{2}\theta = 1$
$=5+\sin^{2}45^{\circ}$
$=5+\frac{1}{2}$
$=\frac{11}{2}=5\frac{1}{2}$
Hence, the correct answer
