1 * 1* 1 = 2/10 * 2/10 * 2/10 * x
x = 125
A. 1:2
B. 3:5
C. 1:3
D. 3:4
72 should be divisible by addition of the above ratio.
Using trial and error method
For (a): – 1+2 = 3, 72 is divisible by 3
For (b): – 3+5 = 8, 72 is divisible by 8
For (a): – 1+3 = 4, 72 is divisible by 4
For (a): – 3+4 = 7, 72 is not divisible by 7
Therefore, the answer is option (d)
A. $503
B. $504
C. $505
D. $506
Cash price = $21 000
Deposit = 10% × $21 000
= $2100
Loan amount = $21 000 − $2100
= $18 900
I=p*r*t/100
I=11340
Total amount = 18 900 + 11 340
= $30 240
regular payment = total amount /number of payments
A. Rs.350
B. Rs.400
C. Rs.573
D. Rs.480
Explanation:
SP = 600
CP = (SP)*[100/(100+P)]
= 600 * [100/(100+25)]
= 600 * [100/125] = Rs.480
A. Rs. 50
B. Rs. 160
C. Rs. 200
D. Rs. 225
Explanation:
Let C.P. be Rs. x.
Then, 5% of x = 350 – 340 = 10
x/20 = 10 => x = 200
A. Rs. 5725
B. Rs. 5275
C. Rs. 6275
D. Rs. 6725
E. None of these
Explanation:
CP = SP * (100/(100 + profit%))
= 8339(100/124) = Rs. 6725.
