(2bi) consumer Ts in equilibrium when (i)MUx=Px (ii) when total utility is at peak, then marginal utility will be zero. given price to be $1.00 per unit, the consumer will be in equilibrium when he consumes 6 units of the goods because the marginal utility is zero (2c) draw diagram (2d) law of diminishing marginal utility states that as more and more unit of a commodity is consumed, there is a tendency for marginal utility ti decrease as total utility increases


4a) -Peasant farming: This is the type of farming which is concerned with the production of food for the farmer and his family.

Principals to Write Proficiency Examinations In Sokoto

The Sokoto State Government Wednesday said principals of government secondary schools in the state would soon write examinations to ascertain their proficiency.

The state Commissioner, Basic and Secondary Education, Dr. Jabbi Kilgori, made this known at the opening of a three-day sensitisation workshop organised by the ministry in collaboration with the state chapter of the All Nigeria Confederation of Principals of Secondary Schools (ANCOPSS), for Principal in the state.

He stated that incumbent principals must write the examinations to ascertain their proficiency and capabilities to manage the schools.

“Incumbent principals and anyone who will be appointed as principal must write such examinations to know whether they are fit to be appointed as so.

“Any of the existing principals who fails the examinations will be weeded out and redeployed back to the classrooms,’’ Kilgori said.

The commissioner pointed out that the principals will henceforth serve for a term of four years which is renewable only once for meritorious performance.

According to him, the state government had instituted a reward and punishment system for the principals to reward excellence, as well as reprimand indiscipline, respectively.

Kilgori stated that these were part of the measures introduced to ensure the successful implementation of the state of emergency on education already declared in the state. In a remark, Governor Aminu Tambuwal, who spoke through the Secretary to the State Government, Prof. Bashir Garba, said the state government had allocated about 28 per cent of its 2016 budget to education.

He emphasised that the move was part of the strategies evolved to revive education in the state.

Tambuwal underscored the need for principals to be disciplined, prudent, innovative and resourceful in managing their schools.

The Presidentof ANCOPSS in the state, Alhaji Abdullahi Marafa, said the workshop was meant to enhance the skills and knowledge of the principals to operate in line with global best practices.

Capacity Building Key to Achieving 10,000mw By 2019 – Fashola



The ministerof power, works and housing, Babatunde Fashola, has stated that the target of 10,000 megawatts (mw) by 2019 will not be realised except skilled manpower needs are addressed in the sector.

Fashola, who emphasised that design, building of plant, its operation and maintenance, can only be carried out by key skilled manpower, underscored the role of the National Power Training Institute of Nigeria (NAPTIN), in the realisation of the 10,000mw target.

Speaking during a ceremony for graduating trainees under the NAPTINS Graduate Skills Development Programme (NGSDP), the minister urged the trainees to brace up to this challenge by developing positive attitude that would enable them to be creative in solving the myriad of problems responsible for the lack of access to power by many Nigerians.

Represented by the permanent secretary, Power, Mr Louis Edozien, Fashola said that there will soon be executive actions on issues around renewable energy, coal, embedded generation and the need for a workable training policy for the NAPTIN.

He also informed that the governmentwas looking at the quest for making the NAPTIN a citadel of quality learning with its proposed post-graduate degree programmes.

Speaking earlier, the director-general of the NAPTIN, Mr Reuben Okeke, had requested the minister to help fast-track the plan to incorporate the training of lower cadre personnels, similar to the now rested National Power Apprenticeship Scheme (NAPSAS) in the sector, to complement the trained engineers that are primarily the focus of the institute.
