Haemoglobin is an important component of _______.

Accepted Answer

Haemoglobin is an iron-rich protein found specifically in red blood cells (RBCs). It binds with oxygen and transports it from the lungs to various tissues in the body.

Question 8

Select the related letters from the given alternatives. DFH : GIK :: MOQ : ? DFH : GIK :: MOQ : ?

Accepted Answer

Each letter in the first term is shifted forward by 3 positions to get the second term (D+3=G). Applying +3 to MOQ gives PRT.

Question 9

The length of the common chord of two intersecting circles is 12 cm. If the diameters of the circles are 15 cm and 13 cm, then what is the distance (in cm) between their centers?

Accepted Answer

Half of the common chord is 6 cm. The radii are 7.5 cm and 6.5 cm. Distances from centers to the chord are √(7.5² - 6²) = 4.5 and √(6.5² - 6²) = 2.5. Total distance = 4.5 + 2.5 = 7 cm.

Question 10

If 9x - [5(2x + 1)/2] = 9/2, then the value of x is?

Accepted Answer

Multiply the entire equation by 2 to remove fractions: 18x - 10x - 5 = 9. Simplifying gives 8x = 14, which reduces to x = 7/4.

Question 11

Amit donated 20% of his income to a school and deposited 20% of the remainder in his bank. If he is having Rs 12800 now, then what is the income (in Rs) of Amit? 9/7/2017 Staff Selection Commision

Accepted Answer

Let income be x. After 20% donation, remainder is 0.8x. He deposits 20% of this remainder, leaving 80% of 0.8x, which is 0.64x. Equating 0.64x = 12800 gives x = 20000.

Question 12

The reaction of Copper Sulphate and Iron produces Iron Sulphate and __________.

Accepted Answer

Iron is more reactive than copper, so it displaces copper from the copper sulphate solution, forming iron sulphate and solid copper in a single displacement reaction.

Question 13

What is the percentage increase in number of students of Commerce from 2012 to 2016?

Accepted Answer

Find the difference between the number of Commerce students in 2016 and 2012. Divide this difference by the base year (2012) value and multiply by 100 to get 13.51%.

Question 14

D and E are points on side AB and AC of ΔABC. DE is parallel to BC. If AD:DB = 1:4 and area of ΔADE is 6 sq cm, what is the ratio of area of ΔADE: area of quadrilateral BDEC?

Accepted Answer

Since DE || BC, ΔADE ~ ΔABC. The ratio of their sides AD:AB is 1:5. The ratio of their areas is (1/5)² = 1/25. Thus, Area(BDEC) is 25 - 1 = 24, making the required ratio 1:24.

Question 15

Sycon (Scypha), Spongilla (Fresh water sponge) and Euspongia (Bath sponge) are examples of which Phylum?

Accepted Answer

Sycon, Spongilla, and Euspongia are all types of sponges. Sponges are pore-bearing multicellular animals that belong exclusively to the phylum Porifera.

Question 16

If a = 73, b = 74 and c = 75, then what is the value of a3 + b3 + c3 – 3abc?

Accepted Answer

Use the formula 1/2(a+b+c)[(a-b)²+(b-c)²+(c-a)²]. The sum (a+b+c) is 222, and the sum of squared differences is 6. Thus, 1/2 × 222 × 6 = 666.

Question 17

The ratio of present ages of Anil and Aakash is 4 : 5. Three years later their ages will be in ratio 7 : 8. What is the present age (in years) of Anil? ?

Accepted Answer

Let their present ages be 4x and 5x. After 3 years, (4x + 3)/(5x + 3) = 7/8. Solving this gives 3x = 3, so x = 1. Anil's present age is 4(1) = 4 years.

Question 18

A train travels 40% faster than a car. Both start from point A at the same time and reach point B, 140 km away at the same time. On the way the train takes 25 minutes for stopping at the stations. What is the speed (in km/hr) of the train?

Accepted Answer

Let car speed be v, so train speed is 1.4v. Time difference: 140/v - 140/1.4v = 25/60 hours. Solving gives 40/v = 5/12, so v = 96. Train speed = 1.4 × 96 = 134.4 km/hr.

Question 19

In the following question, select the missing number from the given series. 2, 5, 17, 71, ? 2, 5, 17, 71, ?

Accepted Answer

The pattern is ×2+1, ×3+2, ×4+3. So, 2×2+1=5, 5×3+2=17, 17×4+3=71. The next term will be 71×5+4 = 355+4 = 359.

Question 20

Faiyaz's birthday is on Wednesday 12th April. On what day of the week will be Shray's Birthday in the same year if Shray was born on 2nd October?

Accepted Answer

Calculate days from April 12 to Oct 2: 18(Apr) + 31(May) + 30(Jun) + 31(Jul) + 31(Aug) + 30(Sep) + 2(Oct) = 173 days. 173 ÷ 7 leaves remainder 5. Wednesday + 5 = Monday.
