Question 4 2.67 / -0
The ratio of present ages of two persons, A and B is 3 : 4. After 20 years, this ratio will become 7 : 8. What is the present age of A?
Solution
Assume present age of A = 3p years
And, present age of B = 4p years
Now, according to the question,
Or, 8(3p + 20) = 7(4p + 20)
Or, 24p + 160 = 28p + 140
Or, 4p = 20
Or, p = 5
So, present age of A = 3p = 15 years
Question 5 2.67 / -0

Question 6 2.67 / -0
If the area of a rectangle is 60 cm2 and its perimeter is 34 cm, then the length of the diagonal is
Solution
We know that,
Area of rectangle, A = l x w (where l is length and w is width)
Also, diagonal of rectangle, d =
But as we do not know the length and width, we can work with another formula to find diagonal, i.e
(where P is Perimeter of rectangle)
So, d =
cm
d = 13 cm
Hence, answer option 4 is correct.

Question 12 2.67 / -0
What is the smallest number which when multiplied by 3600 will give a perfect cube as the product?
Solution
3600 = 2 × 3 × 2 × 5 × 2 × 3 × 2 × 5 Pairing up, we get 3600 = 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5 So, to obtain a perfect cube, we need to multiply 3600 by 2 × 2 × 3 × 5 = 60. So, the correct answer is 60.
Question 13 2.67 / -0
At a certain rate of simple interest, Rs. 700 in 2 years amounts to Rs. 840. If the rate of interest is increased by 2%, what will be the amount after 3 years?
Solution
SI =
840 - 700 = 700 × 2 ×
140 = 14R
R = 10% per year
Then, total amount after 3 years = 700 + 700 × (10 + 2) ×
Total amount after 3 year at a rate of (10 + 2)% per year = 700 + 252 = Rs. 952
Question 14 2.67 / -0
A refrigerator is sold at Rs. 5225 after allowing a discount of 5%. What is its marked price?
Solution
Selling price of the refrigerator = Rs. 5225
Discount = 5%
Let marked price = Rs. x
Discount = Rs. x - Rs. 5225
x - 5225 =
x - 5225 =
x -
= 5225
= 5225
x =
= 5500
So, marked price of the refrigerator = Rs. 5500
Question 15 2.67 / -0
The marked price of a bag is Rs. 5200. If it is sold at a discount of 15%, what will be its selling price?
Solution
Marked price of the bag = Rs. 5200
Discount = 15%
Discount price = Rs.
= Rs. 780
Selling price of the bag = Rs. (5200 – 780)
= Rs. 4420
Hence, (3) is the correct option.

Question 30 2.67 / -0
A number consists of two digits, whose sum is 15. If 27 is added to the original number, its digits get interchanged. Find the original number.
Solution
Let the digit at the units place be x. So, digit at the tens place = (15 - x) Original number = 10(15 - x) + x = 150 - 10x + x = 150 - 9x Now, after interchanging the digits, the number will become: 10x + 15 - x = 9x + 15 According to the question, 150 - 9x + 27 = 9x + 15 162 = 18x x = 9 So, original number = 150 - 9x = 150 - 9 × 9 = 150 - 81 = 69

Question 90 2.67 / -0
The rough ER differs from smooth ER in that rough ER has abundance of _____________ on it.
Solution
The rough ER differs from smooth ER in that rough ER has abundance of ribosomes on it. These are called membrane bound ribosomes and are firmly attached to the outer cytosolic side of the ER. Rough ER (RER) is involved in some protein production, protein folding, quality control and despatch. The rough ER working with membrane bound ribosomes takes polypeptides and amino acids from the cytosol and continues protein assembly including, at an early stage, recognising a 'destination label' attached to each of them. Proteins are produced for the plasma membrane, Golgi apparatus, secretory vesicles, plant vacuoles, lysosomes, endosomes and the endoplasmic reticulum itself.

Question 94 2.67 / -0
Which of the following statements is NOT true?
Solution
A fuse is an electrical safety device that operates to provide overcurrent protection to an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby interrupting the current. A fuse is a short piece of wire made up of a material of high resistivity and low melting point. Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component(s). A copper wire cannot be used as a fuse wire because it has a high melting point. It will not melt easily when a high electric current passes through it and may damage the electrical appliances.
