In a class, 120 students are male and 100 students are female 25% of the male students and 20% of the female students are engineering students. 20% of the male engineering students and 25% of the female engineering students passed the final exam, what percentage of engineering students passed the exam?

ক) 5% খ) 10% গ) 16% ঘ) 22%

ব্যাখ্যা (Explanation)

male engineering student = 25*120/100 = 30

female engineering student = 20*100/100 = 20

total engineering student = 30 + 20 = 50

now,

male engineering students that passed = 20*30/100 = 6

female engineering students that passed = 25*20/100 = 5

total students that passed = 6 + 5 = 11

now,

percentage of engineering students that passed the exam = 11*100/50 = 22%

A total of Tk. 1200 is deposited in two savings accounts for one year, one portion at 5% simple interest, and therest at 7% simple interest. If Tk. 72 was earned in interest, how much was deposited at 5%?

ক) 410 খ) 520 গ) 600 ঘ) 650

ব্যাখ্যা (Explanation)

let, portion with 5% interest be x

then,

5x/100 + 7*(1200 - x)/100 = 72

5x + 7*(1200 - x) = 7200

5x + 8400 - 7x = 7200

- 2x = 7200 - 8400

- 2x = - 1200

x = 600

The remainder when the positive integerm is divided by 7 is x. The remainder is (x+7) When mis divided by Which one of the following could be the value of m?

The combined salary of X,Y and Z is Tk. 90, X earns twice of what Z earns, and Y earns 5 times of what Z earns. What is the lowest salary of the three?

ক) 20,000 খ) 22,000 গ) 25,000 ঘ) 30,000

ব্যাখ্যা (Explanation)

X:Y:Z = 2:3/2:1 = 4:3:2

now, lowest salary is earned by Z, as we can see from the ratio.

Z's salary = 2*90000/9 = 20000 tk

A worker was hired for 7 days. Each day, he was paid Tk. 10 more than what he was paid for the previous day of work. The total amount he was paid in the first 4 days of work equaled the total amount he was paid in the last 3 days. What was his starting pay?

ক) Tk. 90 খ) Tk. 138 গ) Tk. 153 ঘ) Tk. 160

ব্যাখ্যা (Explanation)

payment for day 1 = x

payment for first 4 days = x + x +10+x+20+x+30 = 4x +60

payment for last 3 days = x+40+x+50+x+60 = 3x + 150

now, A/Q,

4x + 60 = 3x + 150

x = 90

M is a girl and has the same number of brothers as sisters. N is a boy and has twice as many sisters as brothers. Mand N are the children of Q. How many children does Q have?

ক) 2 খ) 3 গ) 5 ঘ) 7

ব্যাখ্যা (Explanation)

Let the number of male kids be x.

For M,

number of brothers = x

number of sisters = x

number of girl kid = x+1

For N,

number of male kid = x

number of brothers = x-1

number of sisters = 2(x-1)

now, A/Q,

x+1 + x = x + 2(x-1)

2x + 1 = x + 2x – 2

2x +x -2x =1+2

x = 3 number of male kid = 3

number of girl kid = 3 + 1 = 4

Total kids = 3 + 4 = 7

Forty tiles of dimensions 1 foot × 2 foot each are required to completely cover a floor. How many tiles of dimensions 2 foot × 4 foot each would be required to completely cover the same floor?

ক) 10 খ) 20 গ) 80 ঘ) 160

ব্যাখ্যা (Explanation)

smaller tiles = 2*1 = 2 sq ft

40 smaller tiles cover = 40*2 = 80 sq ft area

now,

area of bigger tiles = 2*4 = 8 sq ft

tiles required to cover the same floor = 80/8 = 10 tiles

A survey of n people in the town Afound that 50% of them prefer Brand X. Another survey of 100 people in the town B found that 60% prefer Brand X. In total, 55% of allthe people surveyed together prefer Brand x what is the total number of people surveyed?

ক) 50 খ) 100 গ) 150 ঘ) 200

ব্যাখ্যা (Explanation)

Sol: 50% (n) + 60% (100 ) = 55% (n + 100) Solving we get n = 100

n + 100 = 100 + 100 = 200
