3136 . The simple interest on a sum of money at 8% per annum for 6 years is half the sum. the sum is-

A. Tk. 4800
B. Tk. 6000
C. Tk. 8000
D. Data is inadequate

View Answer	Favorite Question

Answer: Option D

Explanation:

Let sum is x

So, simple interest will be x × 0.08 × 6

= 0.48x = 0.5x(same is given)

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

Answer: Option A

Explanation:

যেহেতু simple interest তাই আমরা চিন্তা করেই answer পেতে পারি। 
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।

Answer: Option A

Explanation:

Let the integers be x, x + 2 and x + 4

Now, 3 ( x + 4) - 40 = x

2x = 40 - 12 = 28

x = 14

x + 4 = 14 + 4 = 18

B. 10
C. 15
D. 14
E. none

View Answer	Favorite Question

Answer: Option A

Explanation:

The smallest of three consecutive even integers is 40 less then three times the largest . What is the largest of three integers ?

Let the integers be, N - 2, N and N + 2. respectively.

Now, (N - 2) = 3 x (N + 2) - 40

or, N - 2 = 3N + 6 - 40

or, 3N - N = 40 - 6 - 2

or, 2N = 32

or, N = 16

So, the largest even integer = N + 2 = 16 + 2 = 18

Answer: Option B

Explanation:

P+Q+R = 90 tk

Q = 10+P

R = 2Q = 2(10+P) = 20+2P

P+Q+R = 90

P+10+P+20+2P = 90

P = 15

So, Q = 10+P = 10+15 = 25

Now, P+Q = 15+25 = 40

Average of P and Q is = 40/2 = 20 (Ans)
