[@prajwalks7254]

Teaching is all about how you explain things in detailed manner so that even student with zero interest also gets attention on subject

[@luckydewangan5985]

For people in Q3, it says decreases to 8% that means the interest rate in 3rd year was 8%, if it says decrease by 8% then use minus sign, also it is basically applicable for population problems not for CI.

[@nabeelkhan6164]

Decrease means it has reduced from 12 to 8 years , you need not take minus sign

[@eminence_Shadow]

Thanks..I was confused

Sir simple interest and compound interest installment video please

[@vidhanshujain2413]

In question 3, CN decreases for 3rd year so I think there should be minus sign in the formula.

[@shriniwasraut1469]

no question says decreases to 8% that means interest was still positive

[@kritikavashishtha4714]

Same doubt

[@kanishka7045]

Its because it's not a population question

[@rajbadyakar6526]

Beacuse in the second year the interest was 12% , and in the third year it was 8% , which was less than 12% , So here decreases mean , it's decreasing from 12% to 8% .

[@snehabag1118]

Yes I have same doubt

[@sumitroy4992]

Sir first of all very nice explanation. Sir in 3rd question should we not change the sign for decrease in rate of interest to 8%?

[@Prachi-hx3is]

i think he forgot

[@krohith8018]

the compound interest is now 8% so it still accumulates not deducted ,- sign only valid for population problems

[@OvishaSanyal]

Because it's not a population sum

[@Locomotivesofindia939]

but final calculation is wrong , it should be 4565.218

[@jayadidikiclass4582]

Sir here in qstn 3 they have said that R is decreasing by 8 % but u took it (1+8/100) instead of (1-8/100) ........am i right or missing something ?

[@bobbaliharitha7834]

right

[@thedigitalmukulshow]

exactly there is decreasing so it should be subtracting there

[@Manideep969]

No, it decreased to 8% from 12% not -8%

[@ShubhamKumar-wm5xb]

Bro it decreases to 8% from 12% not decreased by 8% so there will be positive sign between it

[@ASH-xv6wj]

There is difference between to and by

[@amithghosh3332]

Sir in 3rd question in third year it is decreasing but you have taken + sign please check it once and correct it.🙏🏻👍

[@WeCanBeCA]

Career ride best channel 😊

[@prathameshkadam3569]

In question 9, find out the the population for the third year and divided it by 1/4 to get the answer. (Works here because they’ve asked the difference, if you were to find out the growth based solely on the third year you would do the following: P3 + 25% of P3, so the difference will be 25% or 1/4 of P3)

[@melginpaul4526]

understand the question properly @Music_waves official

[@chandrashekharchauhan4120]

@Amey Sutar bro the rate of interest is falling from 12 to 8.. But its still rate at which the money INCREASES... the money is not decreasing... Its like India batting run rate falling from 12 runs per over to 8 runs per over... Scoring rate reduces, but team runs are still increasing every over.. The runs are not reducing.. The team score is not falling from say 250 in the 40th over to 210 in 45th over.... Reduction will only happen if the sum deals with depreciation of value of a property or falling population of the town.. So negative sign will only come in these kind of sums where the overall value is reducing

13699.50 is the amount after compounded ,so the compound interest is the compounded amount minus the given amount ,answer is 8669.5. And may be the way he did is correct ,for such type of problems involving mixed fractions (3 (10/12))
