What is the difference between compound interests for 2 years and 3 years for Rs. 500 at 10% rate compounded annually? |
|
Answer» ong>Step-by-step explanation: LET the sum be Rs.100 Computation of compound INTEREST: Prinicpal =Rs.100 R=10% PER annum and n=2 years. Amount=Rs. ⎣ ⎢ ⎡
100×(1+ 100 10
) 2
⎦ ⎥ ⎤
=Rs. ⎣ ⎢ ⎡
100×( 2 11
) 2
⎦ ⎥ ⎤
=Rs.121 Computation of SIMPLE interest: Prinicpal =Rs.100 R=10% and Time =2 years. ∴S.I.=Rs.( 100 100×10×2
)=Rs.20 Thus, difference in C.I. and S.I.=Rs.(21−20)=Re.1 Now, if difference between C.I and S.I. is Re.1, Then Sum =Rs.100 If difference between C.I. and S.I. is Rs.500, Then Sum =Rs.(100×500)=Rs.50000 helpful to you |

find three consecutive numbers if three times the middle number is greater than the sum of the first and the last number by 176 |
|
Answer» wer :- Given :-
To Find :-
Solution :-Let the three consecutive numbers be x , x + 1 , x + 2. According to the question :- 3 × middle term = first term + last term + 176 → 3 ( x + 1 ) = x + x + 2 + 176 → 3x + 3 = 2X + 178 → 3x - 2x = 178 - 3 → x = 175 → x + 1 = 175 + 1 = 176 → x + 2 = 175 + 2 = 177 The three consecutive numbers are 175 , 176 , 177.Verification :-→ LHS = 3 ( x + 1 ) → LHS = 3 ( 175 + 1 ) → LHS = 3 × 176 → LHS = 528 → RHS = x + x + 2 + 176 → RHS = 175 + 175 + 2 + 176 → RHS = 175 + 177 + 176 → RHS = 528 LHS = RHS Hence verified. |

|
Answer» ong>Answer: Let the present ages of father and SON be x years and y years RESPECTIVELY. According to the first condition, x + 2y = 70 …(i) According to the second condition, 2x + y = 95 …(ii) Multiplying equation (i) by 2, we get 2x + 4y = 140 …(iii) Subtracting equation (ii) from (iii), we get ∴ y = 453453 = 15 SUBSTITUTING y = 15 in equation (i), we get x + 2(15) = 70 ∴ x + 30 = 70 ∴ x = 70 - 30 ∴ x = 40 ∴ The present ages of father and son are 40 years and 15 years respectively.Read more on Sarthaks.com - https://www.sarthaks.com/842205/the-sum-fathers-age-and-twice-the-age-his-double-the-age-the-father-and-add-the-age-his-son-the this is your answer You should find this answer helpful |
