Answer: Option A

Explanation:

Tax সহ মূল্য 110 টাকা হলে বিক্রয়মূল্য 100 টাকা
∴
,, ,, ,, 616 ,, ,, ,, (100× 616)/110,,
= 560 টাকা
12% লাভে, বিক্রয়মূল্য 112 টাকা হলে ক্রয়মূল্য 100 টাকা
∴ ,, ,, ,, 580 ,, ,, ,, 560× 100112 ,,
= 500 টাকা।

3124 . The savings of an employee equals income minus expenditure. If their incomes ratio is 1 : 2 : 3 and their expenses ratio is 3 : 2 : 1, then what is the order of the employees A, B and C in the increasing order of the size of their savings?

A. A>B>C
B. A>C>B
C. B>A>C
D. C>B>A

Answer: Option A

Explanation:

Let's denote the income of employees A, B, and C as IA, IB, and IC, respectively. Similarly, let's denote their expenses as EA, EB, and EC.

According to the given ratios: Income ratio = 1:2:3 Expenses ratio = 3:2:1

Now, let's calculate the savings for each employee:

Savings of A = IA - EA Savings of B = IB - EB Savings of C = IC - EC

Now, let's calculate the savings for each employee using the given ratios:

Income ratio = 1:2:3 Expenses ratio = 3:2:1

Let's assume that the common multiplier for both ratios is "x" (where x is a positive number).

So, the income for A, B, and C would be: IA = 1x IB = 2x IC = 3x

And the expenses for A, B, and C would be: EA = 3x EB = 2x EC = 1x

Now, let's calculate the savings for each employee:

Savings of A = IA - EA = (1x - 3x) = -2x Savings of B = IB - EB = (2x - 2x) = 0 Savings of C = IC - EC = (3x - 1x) = 2x

Now, let's order the employees in increasing order of the size of their savings:

Savings of A = -2x
Savings of B = 0
Savings of C = 2x

So, the correct order of employees in increasing order of the size of their savings is A > B > C.

The correct answer is A > B > C.

3125 . The second and third term of a geometric series are 9 and 3 respectivelt ,. The 6 th term of the series is-

B. 1/3
C. 1
D. 1/9

Answer: Option D

Explanation:

To find the 6th term of the geometric series, we can first find the common ratio (r) of the series. The common ratio can be found by dividing the third term by the second term:

r = 3rd term / 2nd term = 3 / 9 = 1/3

Now that we have the common ratio, we can use it to find the 6th term (T6) using the formula for the nth term of a geometric series:

Tn = a * r^(n-1)

Where: Tn = nth term a = first term r = common ratio

In this case, the first term (a) is not given, but we can find it using the second term and the common ratio:

a = 2nd term / r = 9 / (1/3) = 9 * 3 = 27

Now that we have the first term, we can find the 6th term:

T6 = 27 * (1/3)^(6-1) = 27 * (1/3)^5 = 27 * (1/243) = 1/9

So, the 6th term of the geometric series is 1/9.

Answer: Option B

Explanation:

The sum of angles of a triangle = 180∘.

Given: One angle is 90∘(since it is a right angled triangle ) and another angle is 30∘

Hence, 90∘+30∘+Third angle=180∘

⇒120∘+Third angle=180∘

∴Third angle=180∘−120∘=60

Let's say the purchase price of 5 pencil is 1 taka.

Then purchase price of 1 pencil is 1/5 taka and selling price of 1 pencil is 1/4 taka.

Profit margin = {(1/4 - 1/5)/ (1/5)} x 100% = 25%.

Answer: Option B

Explanation:

Hints : The simple interest on a certain sum of money for 2.5 year's at 12% per annum is TK.40 less than the simple interest on the same sum for 3.5 years at 10% per annum

The simple interest on a certain sum of money for 2.5 years at 12% per aannum = pnr = 12 × 2.5 × x the simple interest on the same sum for 3.5 years at 10% per annum = pnr = 1 × 3.5 × x

So, 12 × 2.5 × x + 40 = 1 × 3.5 × x

0.3x + 40 = 0.35 x

o.35 x - 0.3x = 40

o.o5x = 40

x = 800

Answer: Option D

Explanation:

Let sum is x

So, simple interest will be x × 0.08 × 6

So, from the given data, we can't find the value of sum.

We need some more information.

Answer: Option B

Explanation:

ধরি, মূলধন = x টাকা

x টাকায় 10 বছরের সুদ = 600টাকা

x টাকায় 1 বছরের সুদ = 600/10 টাকা

x টাকায় 5 বছরের সুদ = 600×5/10 = 300 টাকা

যেহেতু, 5 বছরের পর মূলধন 3 গুন হয়। সুতরাং নতুন মূলধন = 3x

এখন, x টাকার 5 বছরের মুনাফা = 300 টাকা

1 টাকায় 5 বছরের মুনাফা = 300/x টাকা

3x টাকায় 5 বছরের মুনাফা = 300 × 3x /x টাকা = 900 টাকা

মোট মুনাফা = 900 + 300 = 1200 টাকা

প্রথম পাঁচ বছরে Interest হবে ঠিক দশ বছরের 12=600×12=300.12=600×12=300. 
এরপর পাঁচ বছরে principal এর trebled মানে পরবর্তী পাঁচ বছরে interest 3 গুন অর্থাৎ (300  ×  3) বা 900 টাকা পাবে (Total  =  300  +  900  =  1200 টাকা।
