Question : Find the distance (in cm) between the centres of two circles having radii of 32 cm and 24 cm, respectively if the length of a direct common tangent to the two circles is given as 24 cm.
Option 1: 60
Option 2: 65
Option 3: 64
Option 4: 63
Correct Answer: 64
Solution : Direct common tangent to two circles = $\sqrt{d^{2}-(r_{1}-r_{2})^{2}}$ Let $r_{1}$ and $r_{2}$ be 32 cm and 24 cm respectively. Length of a direct common tangent to the two circles, $d = 24 \sqrt{7}$ cm Direct common tangent to two circles = $\sqrt{d^{2}-(r_{1}-r_{2})^{2}}$ ⇒ $24 \sqrt{7}
Question : A merchant marked the cloth at Rs. 50 per metre. He offers two successive discounts of 15% and 20%. The net price per metre of cloth is:
Option 1: Rs. 32.50
Option 2: Rs. 42.50
Option 3: Rs. 34.00
Option 4: Rs. 40.00
Correct Answer: Rs. 34.00
Solution : Given: A merchant marked the cloth at Rs. 50 per metre. He offers two successive discounts of 15% and 20%. Here, two successive discounts are 15% and 20%. So, the net price after successive discounts = $50×(\frac{100\:–\:15}{100})×(\frac{100\:–\:20}{100})$ = $50×\frac{85}{100}×\frac{80}{100}$ = Rs. 34 Hence, the
Question : Zee and Gee can complete a task together in 24 days. If the efficiencies of Zee and Gee are in the ratio 3 : 8, respectively, then in how many days can Gee complete the task alone?
Option 1: 33 days
Option 2: 55 days
Option 3: 88 days
Option 4: 44 days
Correct Answer: 33 days
Solution : Time taken by Zee and Gee to complete a task = 24 days The ratio of efficiencies of Zee and Gee = 3 : 8 Let the efficiencies of Zee be $3x$ and Gee be $8x$. Total work done by Zee and Gee =
Question : A man travels 400 km partly by train and partly by steamer. He spends 9 hours more time on the steamer. If the velocity of the steamer is 30 km/hr and the velocity of the train is 70 km/hr, how much distance does he cover by steamer?
Option 1: 309 km
Option 2: 371 km
Option 3: 464 km
Option 4: 556 km
Correct Answer: 309 km
Solution : Let $D$ denote the distance (in km) that the man covers by steamer. According to the question, $\frac{D}{30}-9=\frac{400-D}{70}$ $⇒\frac{D}{30}-9=\frac{40}{7}-\frac{D}{70}$ $⇒\frac{D}{21}=\frac{103}{7}$ $\therefore D= 309$ km Hence, the correct answer is 309 km.

Question : Directions: In a certain code language, DJ is written as 410. How will NS be written in that language?
Option 1: 1419
Option 2: 1320
Option 3: 1420
Option 4: 1319
Correct Answer: 1419
Solution : Given: DJ is written as 410.
Write the position values of the letters of DJ to obtain the required code – D→4; J→10 Thus, DJ is coded as 410. Similarly, follow the same pattern for NS – N→14; S→19
So, NS is coded as 1419.
Question : Directions: Select the correct mirror image of the given figure when the mirror is placed on the right side of the figure.
