Question

A and B each have a certain number of mangoes. A says to B, if you give 30 of your mangoes, I
will have twice as many as left with you. B replies, if you give me 10. I will have thrice as many
as left with you. How many mangoes does each have?​

Answer 1

Answer:

A=34 MANGOES,B=62 MANGOES

Explanation:Let no of mangoes with A&B be x and y respectively.

now,according to the question:

x+30=2(y-30).......(1)

3(x-10)=(y+10).......(2)

After solving 1&2 we get,

x=34

y=62

Answer 2

Answer:

Some Important Electricity Formulas are:

I = Q t I = \frac {Q}{t} I=tQ.

V = Q C V =\frac {Q}{C} V=CQ.

R = ρ × l A R = \frac {\rho \times l} {A} R=Aρ×l.

I = V R I= \frac {V}{R} I=RV.

σ = 1 ρ \sigma = \frac{1}{\rho} σ=ρ1.
