Hiii..I’m new in pl thnx my this and other 5-6 answers

3) SI = ₹15600
P= ₹12000
R= 10%

Time= SI × 100/P ×R
= 15600 ×100/12000 ×10
= 13 yrs.

6) Time = 4 yrs.
SI= ₹2100
R= 5%

SI= P ×R ×T/100
P=SI ×100/R ×T
P= 2100 ×100/5 ×4
P=2100 ×100/20
P= 2100 ×5
P = ₹10500

11) Let P= x
R=8%
SI= 54000
Amount = 2x

Amount = P [1+ (T ×R/100)]
2x= x [1+(T × 8/100)]
2x/x= 1+ (T × 8/100)
2-1= T ×8/100
1 ×100/8 =T
100/8=T
12.5 yrs.=T

1200 inches = 30 yards12 inches= 1 foot3 feet= 1 yard3feet= 36 inchesyou can set up a proportion then use inverse operations that looks sorry it looks so sloppy lol
