★ How to do :-

Here, we are given with the principle amount, the rate of interest and the time taken to return back the money. We are asked to find the total amount to be returned back to the bank after the time period. So, we have an appropriate formula to calculate the same. But, first we should find the interest amount and then we should find the total amount by USING the SIMPLE interest and the principle amount.

➤ Solution :-

Simple Interest :-

${\sf \leadsto \underline{\boxed{\sf \dfrac{P \times R \times T}{100}}}}$

Substitute the given VALUES.

${\tt \leadsto \dfrac{45000 \times 9 \times 1}{100}}$

Cancel the zeros in numerator and denominator.

${\tt \leadsto \dfrac{450 \cancel{00} \times 9 \times 1}{1 \cancel{00}} = \dfrac{450 \times 9 \times 1}{1}}$

Multiply the remaining numbers as they cannot be cancelled further.

${\tt \leadsto 450 \times 9 \times 1 = 450 \times 9}$

${\tt \leadsto Rs \: \: 4050}$

Now, let's find the total amount to be paid.

Total Amount :-

${\sf \leadsto \underline{\boxed{\sf Simple \: Interest + Principle}}}$

To find:-

If triangle XYZ~triangle PQR,then YZ/PQ=XY/QR is it correct?suppose your answer ?

Solution:-

In ∆ XYZ ~ ∆PQR , YZ/PQ=XY/QR is not correct .

Given that

∆ XYZ ~ ∆PQR

=> ∆XYZ is similar to ∆ PQR

We know that

In two similar triangles ,

The CORRESPONDING angles are equal.

The corresponding sides are in the same ratio or in the Proportion.

So Ratio of corresponding sides is

33.	A rectangular block of ice measures 50 cm by 20 cm by 15 cm. If ice weighsof the samevolume of water and 1 cubic centimetre of water weighs 1 gm, calculate its mass in kg.please provide a step by step explanation
Answer» Question:- A rectangular BLOCK of ice measures 50 cm by 20 cm by 15 cm. If ice weights 9/10 of the same volume of water and 1 cubic centimetre of water weighs 1 gm, calculate its mass in kg. Required Answer:- Given:- The dimension of rectangular ice block is 50CM by 20cm by 15cm The ice weights 9/10 of the same volume of water. 1 cm³ water weights 1g To Find:- Calculate the mass of ice block in kg. Solution:- We know that:- Volume of a rectangular block = lbh Where, l is length b is breadth h is height Therefore, Volume of the ice block = 50cm × 20cm × 15cm => Volume of the ice block = (50 × 20 × 15)cm³ => Volume of the ice block = 15000cm³ Now, we were given:- The ice weights 9/10 of the same volume of water. Which means if the water weights X units, the ice will weight (9/10 × x)units. Hence, 1cm³ water weights 1g ∴ 1cm³ ice block weights (9/10 × 1)g = 0.9g Now, 1cm³ ice block weights 0.9g ∴ 15000cm³ ice block weights (0.9 × 15000)g = 13500g As we know that :- 1000g = 1kg ∴ 15000cm³ ice block weights = (13500/1000)kg = 13.5kg Hence,the mass of the ice block is 13.5kg

A rectangular block of ice measures 50 cm by 20 cm by 15 cm. If ice weighsof the samevolume of water and 1 cubic centimetre of water weighs 1 gm, calculate its mass in kg.please provide a step by step explanation

Answer»

Question:-

A rectangular BLOCK of ice measures 50 cm by 20 cm by 15 cm. If ice weights 9/10 of the same volume of water and 1 cubic centimetre of water weighs 1 gm, calculate its mass in kg.

Required Answer:-

Given:-

The dimension of rectangular ice block is 50CM by 20cm by 15cm
The ice weights 9/10 of the same volume of water.
1 cm³ water weights 1g

To Find:-

Calculate the mass of ice block in kg.

Solution:-

We know that:-

Volume of a rectangular block = lbh

Where,

l is length
b is breadth
h is height

Therefore,

Volume of the ice block = 50cm × 20cm × 15cm

=> Volume of the ice block = (50 × 20 × 15)cm³

=> Volume of the ice block = 15000cm³

Now, we were given:-

The ice weights 9/10 of the same volume of water.

Which means if the water weights X units, the ice will weight (9/10 × x)units.

Hence,

1cm³ water weights 1g

∴ 1cm³ ice block weights (9/10 × 1)g = 0.9g

Now,

1cm³ ice block weights 0.9g

∴ 15000cm³ ice block weights (0.9 × 15000)g = 13500g

As we know that :- 1000g = 1kg

∴ 15000cm³ ice block weights = (13500/1000)kg = 13.5kg

Hence,the mass of the ice block is 13.5kg

48.

Decrease 94 in the ratio 4:7, what is the result?

Answer»

Step-by-step explanation:

We have to decrease 94 in the ratio 4:7

Let the NUMBERS whose sum is 94 be 4X and 7x .

Now,

4x + 7x = 94

11 x = 94

x = 94/11

So,

4x = 4 × 94/11 = 376/11

3x = 3 × 94/11 = 282/11

Ratio :- ( Rechecking the answer)

376 / 11 × 11/ 282

= 376/ 282

= 4/3

= 4:3
