Question : Directions: Among the following words, which one will come fifth if they are arranged as per their order in an English dictionary? 1. Wink 2. Whip 3. Weary 4. Wing 5. Weigh 6. Weather
Option 1: Whip
Option 2: Wing
Option 3: Wink
Option 4: Weather
Correct Answer: Wing
Solution : Given: 1. Wink 2. Whip 3. Weary 4. Wing 5. Weigh 6. Weather
Step 1: Compare the first letter of each word. Since all the words start with the same letter W, then move on to the next letter. Step 2: The second letter of each word is either e, h, or i. Based on the alphabetical order of these letters, we can arrange them – Weary, Weigh, Weather, Whip, Wink, Wing. Step 3: Compare the third letter of (Weary, Weigh, Weather) and the fourth letter of (Wink, Wing). Wear and Weather will come before Weigh in the sequence as a comes before i in the alphabetical system. Similarly, Wing will come before Wink as g comes before k. Step 4: Compare the fourth letter of (Wear, Weather). Wear will come before Weather in the sequence as r comes before t in the alphabetical system. So, the sequence is Wear, Weather, Weigh, Whip, Wing, Wink.
Therefore, Whip will come fifth if they are arranged as per their order in an English dictionary. Hence, the second option is correct.
Question : Directions: Which two signs should be interchanged to make the given equation correct? 192 × 16 + 9 – 8 ÷ 2 = 5
Option 1: × and ÷
Option 2: + and –
Option 3: × and –
Option 4: + and ÷
Correct Answer: × and ÷
Solution : Given: 192 × 16 + 9 – 8 ÷ 2 = 5
Let's check the given options – First Option: × and ÷ ⇒ 192 ÷ 16 + 9 – 8 × 2 = 5 Solving the L.H.S. of the equation – = 12 + 9 – 8 × 2 = 12 + 9 – 16 = 5 Second option: + and – ⇒ 192 × 16 – 9 + 8 ÷ 2 = 5 Solving the L.H.S. of the equation – = 192 × 16 – 9 + 4 = 3072 – 9 + 4 = 3067 ≠ 5 Third option: × and – ⇒ 192 – 16 + 9 × 8 ÷ 2 = 5 Solving the L.H.S. of the equation – = 192 – 16 + 9 × 4 = 192 – 16 + 36 = 212 ≠ 5 Fourth option: + and ÷ ⇒ 192 × 16 ÷ 9 – 8 + 2 = 5 Solving the L.H.S. of the equation – = 192 × 1.78 – 8 + 2 = 341.76 – 8 + 2 = 335.76 ≠ 5
So, only the first option satisfies the given equation. Hence, the first option is correct.
Question : Two chords AB and CD of a circle intersect each other at P internally. If AP = 3.5 cm, PC = 5 cm, and DP = 7 cm, then what is the measure of PB?
Option 1: 8 cm
Option 2: 12 cm
Option 3: 10 cm
Option 4: 10.5 cm
Correct Answer: 10 cm
Solution :
AP = 3.5 cm PC = 5 cm DP = 7 cm AP × PB = PC × PD 3.5 × PB = 5 × 7 ⇒ PB = $\frac{35}{3.5}$ ⇒ PB = 10 cm Hence, the correct answer is 10 cm.
