Answer:
3÷2
Step-by-step explanation:
First let the required no. be 'x'.
By question,
(2÷3)+2x=3x-(5÷6)
or,(2+6x)÷3=(18x-5)÷6

or,4+12x=18-5
or,x=9÷6
Therefore, x=3÷2
Answer:
D 20 *1.10 * 1.05
Step-by-step explanation:
We have 19.8 tons of wheat. That is close to 20 tons
We increase by 9.8 percent. 9.8% is close to 10%
When we increase, that is 100% of what we had plus the increase, so we multiply by 100 +10% or 110%. In decimal form that is 1.1
20 *1.10
Then the next year we increase by 5.1%. That is close to 5%
We have 100% plus the 5% or 105%, which in decimal form is 1.05
We multiply what we had (20 *1.10) by 1.05
20 *1.10 * 1.05
This is the total amount we have
