Question

800 ka 2 vars ka mishradhan 920 hai yadi vyaj ki dar me 3% ki vriddhi kr di jay to mishra dhan kya hoga​

Answer 1

Answer:

(800×x×2)/100=120

1600x=12000

x=12000/1600

=15/2

new rate interest =[{( 15/2)×3}/100]+(15/2)

={(15×3)/(2×100)}+(15/2)

=(9/40)+15/2

=(9+300)/40

=309/40

new amount of interest= {800×(309/40)×2}/100

=(800×309×2)/(40×100)

=618/5

mishradhan=800+(618/5)

=(4000+618)/5

=4618/5

=923.6
