उत्तर : 2. "32"
व्याख्या :
Answer: B) 32 Explanation: Here the given series follows a pattern that, 22 - 0 = 4 32 - 1 = 8 42 - 2 = 14 52 - 3 = 22 62 - 4 = 32 Hence, the missing number is 32 Method 2 :: The difference between 4 and 8 is 4, the difference between 8 and 14 is 6, the difference between 14 and 22 is 8. So the next difference between 22 and the next number will be 10 since it follows (4,6,8,10 - add +2 each time) Hence, 22 + 10 = 32 is the missing number.

उत्तर : 4. "All the above"
व्याख्या :
Answer: D) All the above Explanation: 1) SO2 2) CH2Cl2 3) PCl3 How to check the given molecules are polar or non polar : If the electronegativity of the two bonded atoms are different then the bond is polar. Although, some molecules contain polar bonds, the molecule may be non-polar. If the polarity of all the bonds present in the molecule are cancel each other then molecule is non-polar. In the given options, SO2 is polar because the dipole moments on the O do not cancel. PCl3 is polar because the P-Cl bonds do not cancel out. CH2Cl2 polar because the C-Cl bonds do not cancel. Hence, in brief, Polar molecules are molecules with net dipole due to the presence of partial positive and partial negative charge. For example, water is a polar molecule that has partial positive and partial negative charge on it. CO2 is a non polar compound. Therefore, all the given options SO2, CH2Cl2 and PCl3 are Polar molecules.

उत्तर : 2. "6, 2"
व्याख्या :
Answer: B) 6, 2 Explanation: Given series is 372, 823, 644, 582, 46?, 8?7 Here the series follow the rule that :372 = 3+7+2 = 12823 = 8+2+3 = 13644 = 6+4+4 = 14582 = 5+8+2 = 1546? = 4+6+? = 16 => ? = 68?7 = 8+?+7 = 17 => ? = 2 So the missing numbers are 6 and 2

उत्तर : 1. "1460"
व्याख्या :
Answer: A) 1460 Explanation: Days in 4 years => Let the first year is Normal year i.e, its not Leap year. A Leap Years occurs once for every 4 years. 4 years => 365 + 365 + 365 + 366(Leap year) 4 years => 730 + 731 = 1461 Therefore, Number of Days in 4 Years = 1461 Days.

उत्तर : 1. "Hydrogen"
व्याख्या :
Answer: A) Hydrogen Explanation: Entropy is a measure of disorder . It will be maximum in gases followed by liquids and least in solids. Hence, here the gas is only hydrogen and it has the highest entropy.
प्र: K can finish the work in 18 days and L can do the same work in 15 days. L worked for 10 days and left the job. In how many days, K alone can finish the remaining work ? 2255 05b5cc774e4d2b4197775002f

उत्तर : 2. "6 days"
व्याख्या :
Answer: B) 6 days Explanation: L's 10 days work = 115×10=23 Remaining work = 1-23=13 Now, work is done by K in one day = 1/18 1/3 work is done by K in 18×13 = 6 days
